Haunted By An Unknown entity

It goes like this for some years now I have been haunted by this unknown entity.
At night is when its most active I hear doors banging my Television Turns on and off
And on the odd occasion I've heard laughter and what is more freaky is that I live on my own.

The other night was the worst in agesi heard a little girl crying and this male laughing.

Well have you been to a doctor yet?

2nd are you a dedicated Satanist?
And what path of Satanism have you chosen?

Or his house could be haunted, but please introduce yourself, so we know what/who we are dealing with.

I think he may chatting BS, either that or he's been watching to many horror films and can't decide which is fact and fiction.

Could be  

I dont know if I would go as far to say this is BS. Sounds to me like he could have a poltergiest, a spirit that gets kicks out of freaking people out and messing with them. Most are not especially evil and wont harm you, however there are some that are indeed malevolent and will cause you harm. I would look more into this if I was you, and try to find out what is going on.

My Old house had a poltergeist in it many sleepless nights, and continuous shenanigans

Thanks Arazel I'm looking into it now.
