Air has a mass.\n\nTrain has a much bigger mass and it's moving.\n\nNewton's law that for every action there is an equal and opposite action means that for as hard as the train is pushing against it, air is pushing back. Air doesn't have a very large mass so a lot more air is needed to stop a train. Pressurized air could stop the train if you could get the train to run headlong into an airlock and jack up the pressure.\n\nAnyway, the air that is unable to push against the engine is pushed out of the way. What you are feeling on the platform is the continuous air current that leads in front of the train as it passes.\n\nThink of a speed boat on the water, the wake of the speed boat is similar to what the air current looks like travelling around the train.

You are in deep and so am I.  The cursor moving on its own thing happens to me all the time.  It freaks me every time it happens, and I swear I can feel a presence.  \n\nOnce when it was moving on its own I put my hand on top of the mouse and I thought I felt a cold hand suddenly on top of mine.

The short answer is that you are mostly feeling the electromagnetic repulsion between the negatively charged electrons in the atoms making up your fingers and the negatively charged electrons in the atoms making up whatever you are touching. \n\nAs some other people have mentioned, this repulsion is actually mediated by photons. To be fair, there are a lot of other interactions as well and they are all governed by the laws of quantum physics. However, to a first approximation it is the electrons that are responsible for what you are "touching".\n\nIf you are interested in further reading and feel comfortable with your math skills, you might find a copy of Physical Chemistry by Atkins. It's a good intro to quantum mechanics, and it addresses many of the issue involved here.

I believe it has something to do with your cerebellum being able to detect expected and unexpected sensations. A reasonable explanation can be found here: http://science.howstuffworks.com/question511.htm

On Christmas Eve many years ago I lost driving in Caracas.  When turning around in a blind alley, I bumped into another car, and when I got out (stupid), four guys got out of the other car and threatened me with a knife and a couple of broken bottles.  Two of them jumped in my car and tried to drive off, but I jumped in the car with them (even more stupid) and I'm punching and kicking these guys while they're trying to drive my car (how stupid is that). My car ended mashing into a tree and the two guys jumped out and fled.  They were so freaked out by this crazy gringo that they even forgot to take my wallet.  \n\nSometime during this fight I felt a sharp pain in my shoulder.  One of the guys had stabbed me ... I don't know if it was with the knife or bottle.  I still have a scar on my shoulder from the incident several stitches ... it was not a wide slice, but it was a couple inches deep.   \n\nAs for how it felt, it was strange.  Other than the initial sharp pain, like being bitten by a large animal, I didn't notice any pain at all during the fight ... I was all adrenaline.   I was more furious than afraid.    Getting stabbed is not like getting hit on the head (I've had three concussions in my life playing soccer) ... you don't lose consciousness at all (unless you get stabbed in the heart or neck, which cuts off blood to the brain).  In fact, the opposite happens ... you start thinking fast and hard.  That's the nature of adrenaline ... you are completely focused on surviving the moment.  You don't have time to assess your damage or go "OMG, I've been stabbed."\n\nBut then afterwards, when these guys had disappeared, and I looked down and noticed my shirt covered in my blood, I suddenly realized I had been stabbed, and I felt a sudden adrenaline chill ... literally cold.  I remember being surprised ... even moreso that it didn't hurt that much despite the amount of blood.  I felt a bit of pain raising my shoulder.  I felt a little bit faint, but I don't think that was from loss of blood as much as just the sudden realization of "Are you nuts?!  What were you thinking?!"  A very strange set of emotions.

The Train dream:\n To dream that you are on a train, is symbolic of your life's journey and suggests that you are on the right track in life and headed for the right direction.  Alternatively,  you have a tendency to worry needlessly over a situation that will prove to work out in the end. \n{from my dream dictionary}\n\nAs for the dream with your grandmother in it....I believe it is their way of communicating with us sometimes. Do you know at what time your grandmother died? Was it approx, around 3:40??

I'm not an expert at this, but my initial feeling was that you must be feeling guilt about something.  I don't know who the girl may be representative of -- just someone that you care about, I guess. The strangers may represent people in general, and that you're worried about their opinion of you -- especially since you've done something you're feeling guilty over.  Your feelings of helplessness may be represented by the unresponding driver and passenger, and maybe your impression of the world in general...that it's a cold, unfeeling place.

I am sure someone cleverer will come along and shoot holes in this but I think this has a lot to do with Newton's 3 Laws (Newton being a clever dead bloke).\n\nForce: When you kick your sister in the shin you are using force\nMass: If she is fat, she has lots of mass\nInertia: Being fat, she will not be able to chase you. She has inertia. \n( Example from - http://www.allworldknowledge.com/newton/index.html)\n\nSo you are on the train and you are moving - its worth remembering that gravity (the force which keeps you on the floor) only goes downward not along. You on the train are moving along and the 'force' of the train going along, keeps you going along. Get it?\n\nWell you're still going along, watching the world go by, and then you jump.\n\nBy jumping you're still going along with the direction of the train thats one force. But when you start coming down it's the gravity pulling you back, as another force. The train moving you along hasn't changed, you just have two forces one pulling you down (the jump) and one pulling you along (the train).\n\nSo you end up in exactly the same place. With a few miserable commuters.

It probably means your not safe at your current station in life. It could also be some kind of warning. And then again, its probably just a dream.

It is a force that pulls you to the earth.

i need some more details to answer. do you feel the tapping at the mid-point of your chest, a bit above the epicardium and spread over 1--2 sq inch area or is it something different? if the answer is yes, then you have felt the centre of a life force (praan) which controls our feelings like love, hate, kindness etc. and it is normal. try to feel it more and concentrate on it. if you wish to learn some more you go through the letter ' SEVEN NERVE CENTRES' in my group http://groups.yahoo.com/group/gita_upanishadrahasya

it is LOUD, and even if your house isn't damaged, everything is vibrating.\n\n\nIt sounds a lot like a train going by right outside your window.\n\nAnd afterward, there are tree limbs and odd things lying everywhere.

I don't know but that pisses me off too. I guess it makes me uncomfortable when the person in front of me stares. My logical guess would be that the train goes in different directions during different parts of the day. When the train is going one direction, they have to bring it back at one point. So they make the seats where whatever direction it's going in, you can see it at different times.

the tectonic plates that shift happen  underground, if your lucky to see a plate shift at ground level your truly lucky, these plate shifts cause earthquakes so please be careful.

You did the right thing definately always listen to that feeling you had. Call the police department and ask what it takes to get a restraining order and stalker laws in your area. Look into house alarms and always keep your eyes open!  Have a  friend stay over if you have more trouble, buddy system when you leave to work call a family member or friend keep someone aware of you movements at all times so if something happens someone will come check on you or call the police, vary your routes home from work change them up so you aren't as predictable,  and always have a cellphone on and  erady to call someone if you have trouble. An ounce of prevention is worth a pound of cure don't let that scare you. Having a dog may help too. Be careful and don't second guess yourself if he gets worse it is not your fault nothing you did or will do caused this. He's most likely sick protect yourself. Consider a self defense course too scary but may come in handy with him or if you take a trip to NY, NY be safe!

You would be hurt more.  If you are in contact with the elevator, It would cushion and defray some of the impact force.  If you are in the air, it's just you and the ground......
