So I've done this thing since before I can remember. I'll be lying in bed, and it will suddenly feel as though the bed is shaking. Now, I've been in the same house for 18 years, and so I always thought it was just the washer or the dryer shaking the house (my house is like that -- if someone jumps in one room you can feel the tremors across the house). But now that I've gone to college and am living on the third story where the washer is off during the night, this is still happening and it's sort of weirding me out. I've been looking for it online, but there doesn't seem to be any professional information on the subject. Mostly there are casual forums talking about it, many of them wondering about demon possession and the like.

My mom says that this happens to her also, though she has only noticed it recently. One of my friends says it's a normal thing that people just do. (I thought it was the bed shaking, but apparently it was my body.)

So I just thought I'd ask if any of you have experienced this or something similar. Feel free to discuss other sleep disorders, too.

(I'm assuming this is the right place for this topic. If not, let me know and I'll see about moving it > <)
