knowing a spirit named six

For the last 4 years i have been communicated slightly with a spirit... what i got from him, the spirit is male, his name is six, he won't take a side in a conflict in the spirit world, he wears a fire pendent, a pendent that is the alchemy triangle, for fire in a silver circle, he wears a black suit, with red under shirt made of silk he rolls up his right sleeve, he has brown hair somewhat long and brown eyes, i have no relation to him but he was following my father too...
he passes in and out of my dreams, he also shows himself to me as a shadow or i sense his presence like a huge gathering of energy... my question is that is it bad to know a lot about a spirit/ghost. Although he seems normal, he acts like a older brother to me, should i trust him? Should i just ignore him, my friends that believe me think that he isn't worth trusting and my friends who are skeptics think i might have schizophrenia or something( although 100% of schizophrenics don't know the symptoms or notice something wrong if i were then i would know i even took psychology and studied the human brain for 2 years), i have seen other spirits but when they come six runs away, he avoids meeting other spirits at all costs and then the other spirits talk to me about me and six's relationship, although after wards i can't remember what they said in that conversation and all i remember is that they were there they started talking then it goes blank. And when i look into information and try to figure six out, he gets mad at me and leaves me for a little bit then it feels like i am missing a part of me, but i sleep better when he is gone. He said he stays with me for no reason not to protect me or to hurt me and that he doesn't love me or hate me but i remind him of himself that i am like him and that is why he follows me... I almost think that he is using me in some way but i don't know

I don't want to make a story long by putting another one on, but i was confronted by spirits in what had to be a dream to make it logical but there was evidence all round it wasn't when i "woke". please read the ** first

I went to a camp last year at a college... and half way through i noticed a lot of spirit activity. I would tell my psychic friend about six she would say she sees him standing behind me but her description is wrong. Then as though he walked past there was a breeze, foot steps, papers were knocked off tables in the path, and all looked exactly like something a person would do if they were mad, i even experimented in doing the same action of walking and knocking stuff off in the exact way that it happened and it was perfectly replicated and we tried a fan and it didn't work. My friend said "six" looked mad, i should have suspected he wasn't there when i had a lot of sleep, i slept well there.

**That night i went to bed at 11 because i was goofing off in the dorm room hall way. i layed down and it felt like 30 minutes of just laying there, and i looked at my phone and there was a text message... it was my mom telling me that i need to look out for myself that she had a dream that someone was going to hurt me, i leaned out of my bed rubbed my eyes and checked the time, and it was 1:30 in the morning. I looked to see if my roommate was sound asleep, and she was but i looked to our wall and our mirror light the one above the mirror, was green.I thought we had construction paper up there blocking the light and i got out of my bed onto our cold tile floor kicked my cloths under my bed cause they were all over and checked the light and i looked at my own reflection in the mirror in front of me.I saw my eyes they stood out i was about a foot away from the mirror and i saw cross like plus signs in my eyes, the edges of my vision became dulled, and i looked closer and saw that the black pupil crosses dilated and contracted. i screamed holy s***. and i turned around and there were 2 spirits a girl with long white hair that look young and beautiful, and another that was a guy with black hair, he fit the descriptions my friend said of the spirit she thought was "six" they began by telling me they named me______... then my memory faded it went black i woke up in my bed at 9:00 class started at that exact time... I looked at my phone and i got that text message at that exact time no lie and when i woke up my room mate was sleeping and all my cloths were under my bed like in my dream and there were shoe prints on my blanket,also my phone was below the mirror when i had on the heater next to my bed when i went to sleep. and our light was burnt out... i can't tell if it was a dream or not i assume it really happened although my no one heard me yell or saw people in our dorm room that has 3 locking systems on it to which only me and my one roommate can unlock to get in. I called my mom that morning and she said i called her at 1:30 right after i got the message and she told me she was worried about me and that she thought i was in danger of something and i ensured her i was mature enough to take care of myself. And i told her about that dream"reality?" and she said it was just a dream...
