Nightmares?? Please help.

Hey ladies. So this might be the dumbest thing you read all day but this is my last hope honestly. And I know it’s not about sex/relationships but I didn’t know where else to put it.

I’m almost 19 years old (will be in June) and ever since I was about 5, I started having dreams of Michael Myers (yes, from Halloween). I made the mistake of watching the movie when I was way too young and I had nightmares for months afterwards and still do every once in a good while.

Here lately, different nightmares have sparked up and usually I can’t remember what they are, I just know I had one because I wake up not being able to breathe.

I didn’t go to bed till about 2:30-3 this morning because I didn’t get home from work till late (I work 2nd shift), so I just woke up (it’s 11:51 as I’m typing this). I woke up from having a nightmare about my grandma getting remarried and my friends and I murdering someone and having a lesbian experience at the rehearsal dinner. If it makes any difference, I’m not friends with the girl at all anymore and the other ones I didn’t even recognize. Every time I would try to wake up from them, I’d fall back asleep and the dream would pick up right where it left off.

I need some advice because honestly I’m traumatized and don’t know where these nightmares are coming from or why I’m having them so frequently. Any advice would be greatly appreciated. Thanks in advance.
