Thanks Tkindle!

Well, last night I totally forgot to say my mantras.. ugh.. but somehow I managed to wake up after about 3 hours and 30 minutes of sleeping. I don't think I dreamt, though.
I also woke up about 2 hours and 15 minutes after that. I decided I was going to WILD, so I got up and went to the bathroom. I got back in bed, and just lay still on my back. (in my previous WILDing attempts, I found that if I lay on my back, I can't fall asleep as fast, but I guess it gives me enough time to snap back into awareness before I fall asleep completely) Well, about 5 minutes into focusing on my breathing and still laying on my back, I got extremely uncomfortable. Like so uncomfortable it was almost painful. I guess I need to just ignore that. But I didn't.
I wound up on my side, focusing on my breathing. About 5 minutes into this, there was a time here where I was completely focusing on how my breathing was going on inside my body, and the coolest thing happened. I felt very very tiny vibrations throughout my body (I don't know if this was the onset of SP or not..), and my hearing deafened just a little bit. (Like it was trying to switch from external to internal) It also felt like I was floating on water for a few seconds. (This feeling was almost like how when you hold your breath, and then let go, you feel kinda light headed and relaxed)
But then that sensation went on for a few more seconds and then I fell asleep.

So, anything on what happened last night?
