Once you realize that you are dreaming...

What happens to you guys?

A number of things happen to me, those things being

All of a sudden, movement will be very slow, like I'll try to walk but it will be very slow and hard

Everything will just fade and I'll wake up almost instantly

I spin around really fast in my dream and try to imagine somthing to dream about(I dunno if this works but I read it somewhere)

The last 2 nights though, I have realized I am in a dream and this is what happens. I will automatically spin around without even trying to and I'll spin until I lose balance and fall over, then everything goes white, there will be infinite white space. At this point I always realize that I can wake up if I want or I can stay there and eventually people and objects will start to fade in and I will still realize I am in a dream. I haven't been able to stay in the dream for long or alter what I am dreaming about though.
