This has happened to me twice. The first time I was shifting dream scenes constantly but I questioned lucidity when was on the kitchen floor of where I live wrapped up in a blanket like I'd been sleeping there. A friend of mine's father was there cooking something and trying to wake me up... I questioned if I was dreaming but felt so tired in the dream that I just closed my eyes, feel asleep, and awoke in another dream sequence totally unaware.

The second time I was in a the car with a friend and a bunch of odd stuff was happening... I felt like I didn't want to deal with it and wondered if it was a dream then got tired and fell asleep. This time though I awoke in the same dream sequence but again totally unaware and swept back up in the dream.

Anybody experience something similar? Have any ideas why this is happening? My initial thoughts are maybe I am actually too tired to become Lucid and need the unaware sleep... or maybe I am just not stable or aware enough to be Lucid at that particular time.
