Strange Dreams and Scary Things

I'm having these very strange dreams lately you could probably say disturbing. I really think I'm being possessed by something...

The dream starts out as me and some friends walking somewhere and this black demon....eyes fully black and piercing starts chasing us. I didn't know where we were running. Its eyes would change and I could hear it saying something like it killed all the people besides me, and a friend then it took control.....

I was carrying a gun and it starts turning at my face and it fires I've been having dreams with things like that since I was 5 idk what it is the old dreams where bad as well...it was like I was awake but not ...I heard this roar or some yelling it was none stop and I would awake parents around me I'm shaking like crazy holding my ears....

I had that dream tell I was 11 and we had the house blessed but stuff is still happening and it feels stronger now and seems to be fighting the blessing ....I'm honestly scared I'm looking behind me all the time I see little things and me and my mother sit in the living room and hear cracks snaps and banging and it's unexplainable I need help of some kind please! Tips anything!

Note:I'm getting this burning sensation while typing.
