I woke up at 6:30 AM this morning (I always wake up at completely random times during the night, It comforts me since I don't have to set an alarm or anything if I want to try a FILD, MILD or w/e.)

Well I tried to FILD with Hargarts method but everytime I almost felt asleep I got so excited by the thought of having a LD that I woke up. I was almost certain I would get a LD if I would fall asleep since I remembered my last dream and I was trying to get back into it, I also tapped my fingers and thought about doing a RC after about 30 seconds. Anyway I couldn't fall asleep for about an hour when I gave up and ofcourse fell asleep almost instantly.

Now my question is, when I was trying to FILD I felt this weird falling sensation, like I fell through my bed. Is this normal? I woke up from the excitement and did a RC as soon as possible only to find out I was still awake.
