questioning my own sanity

this dream or nightmare i had was too realistic and too unnerving for me to just let it pass by. in the dream i wake up to me running for my life through some woods with the tall skinny guy coming after me and i keep looking back. and then another one of him just standing there staring and he does this twitchy thing with his head it was unnatural and disturbing and i keep running and i guess he stops and i tripped over something i cant remember what. as i fell and looked up on the tree branches where people with there whole chest and stomachs peeled away and impaled on the tree branches i get up to the two freakishly tall ones just staring at me and i cant explain it like a voice in my head type of thing. i heard that hypnotic voice like they were arguing or something and then silence and it spoke directly to me telling me if i still want to play a game? the prize would be him fixing me and i passed out from the headache i started getting. i woke up again sweating and coughing up blood and with a pounding migraine.. i honestly think im losing my distinction between reality and hallucinations.. if he even is a hallucination.. after the last few days i don't think its safe at my friends anymore. i don't know if anyone will even believe this. or whats going on. i just wish there was someone to talk to about this.
