I'm new here so sorry if this has been asked or if I'm doing this post question wrong.

Just to give a quick idea of the situation, I stopped practicing lucid dreaming since I've been in collage. I've had only about 7 successful fully lucid dreams in past 6 months, each very awesome. Unfortunately, I stopped practicing since I've been at college, for about 2 months.

Today, I decided to take a nap and listen to Alpha binaural beats. Somewhere between 15-30 minutes into the nap, I notice people barging into my dorm, realizing its a dream. I did the rubbing of hands, spinning in circles just to get a feel for the dream.

The problem is that for some odd reason, I had to fight to keep my 'dream eyes' open. When walking through this huge and fancy place, I was getting really tired and my eyes kept closing. I tried feeling the environment around me (gather more awareness), but that didn't make me feel more awake in the dream. At one point, I gave up and imagined a nice couch and laid down/sleep. After that I don't remember anything.

So can anyone tell me if it is they felt sleepy in a dream that you are conscious in? To the point where you are fighting to keep your eyes open? I was really really tried to begin with so maybe that had something to do with it.
