I was listening to some relaxation Binaural beats last night while relaxing in bed. Suddenly I had a feeling like I was sinking into my bed and it went VERY dark, I could hear some ominous ambient sounds, probably just the humming from my laptop though. I got really scared, I thought I had accidently fallen asleep and was going into a lucid dream. I don't have nightmares anymore but I still got scared of having a true LD. But then I realised I was still very aware of my surroundings, my body felt like it was sunk into the bed by maybe a foot or so, but I knew I was lying down normally on my bed.

Is this an OBE, or did I just get too comfortable?
