Thread: Questions about an experience tonight

I have some questions about something that happened to me tonight.

After waking from a non-lucid dream, close to 5 am, I decide not to move, to see if I go into a lucid dream. I try not to focus on it or throw away other thoughts. I simply let my mind think what it wants.
After a few seconds, i start to feel vibrations and my heart beating faster. I think something will happen but i try not to focus too much on it. What happens, happens.
Gradually, i see an image forming. I see the top of a tree, green leaves move with the wind, vivid colors ... I realize that i'm dreaming.
I have not concentrated on practicing some special technique. I must have made one accidentally. What was this technique i've done?

Another thing is about what happened to me in this dream.
I fell asleep lying on my back and my head to the side. On the dream I watch the tree, in the same position i had fallen asleep. I'm hovering beside the tree. I can not move. I know my body is out of the physical body. I focus on moving only in the dream but I can not.
Suddenly, I start to get away from the tree in the same position and i pass through the scenario. I go through a field with trees, then some land, then some warehouses, kinda like an industrial area. After a few seconds I wake up.
Why couldn't i move in the dream? Why was something pulling me away without my control? Could i have done something?
