How do i get rid of an entity that bothers me while im asleep?

Okay, I tried to talk to other people about it, but everyone is just as skeptical as I am. There is this entity thing that used to look like a shadow but now it seems to take on more form... First time I couldn't move and it felt like it was raping me. It got off of me and I could finally move and ran to my parents room. (I had an energy drink that night.) anyways I went online the next day to see what it was, I saw something about these things called shadow people and asked advice. I was told not to drink an energy drink before I go to bed again.. They said it was probably causing me to lucid dream. Anyways, I’m not going to lie I kind of liked the whole ordeal and so I drank an energy drink again. it came to me again except this time I could move but I just didn't do anything. it then left me alone for a few days... I was sad, but then it came to me again then again another night... I thought this just happened in my room, but three times when I was laying in my parents room it came to me. (I asked it why it kept visiting me, it said "because it can") I didn’t mind it really, it felt good... so I didn’t mind it. then just three weeks ago maybe, there was two of them.. one felt like it was having with me while the other put this knife in my mouth. I tried to banish it away from me once during another time, but it just got in my face, which scared me so extremely, but all it did was smile and kiss me. (its mouth tastes stale and it has pointy teeth) I hadn’t been fighting it off lately.. till just maybe a few days ago.. when it told me "if I didn’t start fighting back it was going to slit my throat" so I did.. it had me pressed against a wall. it scares me, but yet I still want it more each time... I don’t know. I can hear it breathing when its on top of me now though... it pants like a dog does. just an hour ago, its 3:46pm here, I went to go take a nap.. it came to me and it started having with me like it always did, I loved it, but then it freaked me out by trying to make me swallow these metal things. I don’t want it to bother me anymore, all it does is scare me to death… I’m scared that at one point it will kill me in my sleep. That’s another thing.. It doesn’t feel like I’m asleep or awake.. Its kind of like I’m in the middle. I don’t know. I don’t want to want it.. Someone please help. And don’t tell me to go to church or pray more… I need help help, not faith help. Please.
