Need help in classifying my recent experiences

[mathyou9]

Preface: I've never intentionally initiated to have lucid dreams. I have experienced them occasionally (once every few months.) Since I have never made any attempt to initiate a lucid dream, no reality checks were used. In the lucid dreams that I have had, I simply "just knew" I was dreaming. Anyway, on with my post. This past week I have experienced parts of dreams that I'm not sure how to explain (or what to call it.) First, on one partcular night, I put a pleasing song on repeat (playing over my PC speakers) to keep my mind from wandering so that I could fall asleep easier. Of course, eventually I did fall asleep. However there were multiple time when I woke up during the night; and being awake, while just lying there, I actively listened to hear the song playing. But for two or three seconds, I heard nothing. After this brief silence, I heard the song pick up mid-verse. Each time that I woke up (or thought I woke up) I heard only silence. And when I did hear the song, it picked up mid-verse (so I know it wasn't just me coincidentally waking up at the beginning/end where brief silence would be expected.) So what gives for these instances of hearing no music? Was I awake or did I just think I was awake? --- And yesterday, I [mostly] woke up, but seeing that I had only been sleeping for six hours, I decided to get back to sleep (eight hours is my norm.) But before I did, I imperatively felt the need to take one of my pillows down the hall on placed it on the floor. Tangentially, had I kept a dream journal, I could tell you the reason why I felt the need to do that; all I can remember now is that I was finishing up something I was dreaming about (like I was trying to beat a deadline in placing my pillow on the floor down the hall.) In my mind, once I set the pillow down, I knew I could get back to bed. Then a couple hours later, I woke up. But I forgot about the entire pillow incident at that point. When I finally got out of bed, I walked down the hall to see my pillow neatly placed on the ground. I just laughed out loud, because just the sight of it sitting there sparked my memory of actually putting it there (it was something I vividly remember doing.) Obviously I was still in a dream-like state when I felt compelled to place my pillow on the floor. But obviously I was awake since it is something I vividly remember doing. What exactly would it be called or classified as? Thanks.
