Automatic Movement before Wake

So today i was feeling a building dizziness and i only wanted to lay down a bit, after i leaned on my bed the feeling intensified and when i realized i heared a scream, it was me, i was about to fade out and my body run like 7 meters until i crashed into my byke, that was the moment i regained my concience, i hurted myself slighty but that event let me in a very heavy mood, i think that 1: I wanted to go outside to take some air and my subconscious took the only way out to prevent my body and mind to faint and 2: It was a very violent movement, so i think i was just losing my mind. Any words? Thanks.
