Has anyone else here ever had a dream where you are pretty much lucid, but mistake the dream state for a near death experience?

I've had quite a few of these now. The funny thing is how absolutely relaxed I am about entering these states. The first time it happened I just tried to go through a wall for a while. The last time it happened I found that I was trying to make the dream vivider and vivider while getting deeper and deeper into my subconscious.

Its an interesting state to experience. I mentioned it to a flat mate and apparently she's experienced it too.
