Oh.....My.......God. I have had the exact same thing you are describing word for word since a very small age and sometimes I will wake up in the middle of the night and it will feel like everything coming closer and then going far away. going in and out repeatedly and my body and my fingers feel like they're big one second and then small the other. It's very weird and annoying at times and I mostly get it when i'm in bed with my quilt or duvet wrapped around my neck.
