This happened a few weeks ago. I went to bed on my side and unexpectedly started to feel vibrations and the familiar tug and pull. I immediately set my mindset to be fearless and determined no matter what. I started to feel the tugging intensify in my head and asked my spirit guides to help me. I kept repeating that over and over and heard a ripping noise, like velcro as my astral head pulled further and further away from the pillow. I finally was able to sit up in bed but couldn't see a thing! I knew this was a common occurence so I thought I would just wait and see what happened. Then I felt my husband's arms wrap around me and lay me back down. Then I woke up and he was snoozing, so not my husband at all, lol. I assume it was my own subconcious pulling me back in. :).
Hee hee, these feelings are normal. There's always something trying to stop you however daft it seems, just carry on knowing you can walk away from your sleeping body.
If you do this as soon as you can, you'll be out and about with far more control. You actually made it out, had you got up and away, this post would have been about your house and whatever was different.
Good progress.
