Astral Projection Dream

I was working on my astral projection and fell asleep during meditation in real life. This was the dream I had.
I was in a room that may have been mine, but it looked different. Brighter. My bedroom door closed by itself, and I figured it was just air currents. Then I found myself wondering if maybe I was astral projecting and the door had something to do with it. I was in bed alone and wrapped up in a big fluffy blanket and wearing a jacket. It was too hot and I was sweating and overheating, so I took my jacket off and tried to meditate and astral project some more. I felt myself start to float, like I was actually leaving my body, but then the blankets got tangled around me, holding me down. The comforter felt like it had gained several pounds and was actually holding me down, so I tried to fight and kick it off of me, but I could barely move it. It was getting hard to breathe, so I gave up and relaxed again. Then I woke up.
