There is a being who communicates with me through touch
In the past it identified as God but I now know it was lying
I believe it is a kind of Tulpa that I accidentally created (through various means)
I believe that I created it but still consider its presence a kind of demonic possession
Either that, or it is a kind of evil spirit that has entered my mind
(unless all evil spirits are actually Tulpas??? - but if this is the case then we know Tulpas can be banished by an exorcism as exorcisms can banish evil spirits!)
I don't know, but I want it out of my head!
I believe that an exorcism may be able to make it go away
I see you label yourself as Christian. Are you? If so how did you become a Christian? And when, in relation to this problem?
This is important because if you were a Christian prior to this, by Christian I mean one who has come to Jesus Christ as Lord and Saviour, and so are born-again, then the Holy Spirit, has taken up residence in your spirit. And no demonic spirit can move Him.
If this problem occurred before you were a Christian, as I described, and you then became a Christian, as I described, then any demonic spirit or spirits would be removed. The Holy Spirit would remove them.
Have you brought this up before members of your church? Do they agree with you? Have you asked for their prayer concerning this? Not an exorcism so to speak, but their prayer concerning this.
The Spirit world is real and the born-again Christian can come under severe demonic attacks upon his spirit. But they cannot possess his spirit.
Understand also, if you are not a born-again Christian, and you do find someone to perform an exorcism, and it appears to work at that time, there is no guarantee it won't return, as you have not the Holy Spirit. If you are not a born-again Christian, and now become one, then the spirit must leave. He may return to oppress his former home but he cannot possess anymore as the Holy Spirit is there.
Sorry for so many questions, but they need to be asked. I can't stress enough the importance of other believers in your fellowship knowing your problem and praying for you concerning it.
Does this problem affect your voice? Affect your body? Do you lose control over your body? I ask this because you said it is in your head.
