Deep Inside The Lucid Dreamer's Subconscious

I'm having a hard time remembering how I got to understanding I was dreaming. I was in some room with many windows and a high ceiling. My understanding is that I'm in some building that is supposed to be recreational for kids 10-18. So I'm in this room, and I realize I'm dreaming and there's no one else in the room. Immediately after I figure out this is a dream, the dream starts to collapse and the room is getting dark. I start shouting "clarity now!" as I'm looking up at the ceiling that starts to get fuzzy and darker.

The dream exits out and I'm in dark matter alone with my thoughts. I'm thinking to myself 'did I cease to exist? this isn't right...' and then I feel my body land onto something under me. Of course it's me laying on my bed, but I can't see anything and I'm unable to move. I keep breathing heavily trying to wake myself up but nothing is working. Suddenly, I emerge into this really bright room sitting on a bed. The walls are covered with long streaks of blue, red, and orange and the ceiling seems to open up into the bright yellow sky. I take one look at this place and conclude that the last room I was in was simply a dream and that now I'm actually awake. This place seemed too real to be a dream... this is experience was surprisingly very freaky and scary for the amount of stuff that didn't happen.
