Weird and Very Strong Slippin Out of Body

[FistOfFury]

You know that slipping/falling sensation that happens when you're not paying attention and then you catch your astral body trying to get out, and then you slip back into your body? (what is this called anyway? Is there a name for it?) Well, anyway, I get that from time to time sometimes when I'm waking up or about to fall asleep, but this time it was really weird. I was lying down and feeling really drowsy, and then I get the sensation, but it was REALLY REALLY strong! I mean, it felt like I was being slingshotted to the other end of the universe or something lol [xx(]. Then I tried to fall asleep again, and it happened again, with the same intensity. I wasn't expecting it to happen a second time, so I was really surprised, I just about jumped up into the air. Anyone know what's going on? Is that normal? I never felt them so strong before.
