Ill be w/ friend on a walk and usually my friends will go into an area that i cannot go to due to physical attributes: I am short and cannot go up a steep hil, because i cannot reach a branch for example my vision cuts out into blackness, except for small pieces of vision, usually in corners, suddenly i am surrounded by thorns, like a tall hedge, my friends leave and i am left alone, my vision goes from blurry in some areas but black for most, suddenly can hear something stalking me from the shrubbery and it is a small skinny human, he kinda looks like Sméagol from Lord of the Rings, and then i will wake up... please explain this
