Dreams are so amazing, like you have to be aware of your mental state, and yet also be creative with what you do with them, and still work it in a way that youre not overly active in your thoughts to wake, or too caught in you head and feeling sensation , as that causes paralysis, well for me anyway. 

I couldnt watch the trailer you posted, but its just that I cant deal with scary movies or FPS type games solely because of my dreams and how things directly and indirectly influence my state of being. 

Im never a winner in my nightmares..

I would love to hear more... 
Please tell me more..
