Spirit Almost Took My Life

I probably had the worst nightmare alive.

The worst night of my life.

I knew that through a couple of days a sprit has been attached or beign called by me somehow subconsciously.

I would use a pendulum dowsing board to communicate with other spirits and ask them questions.

But this particular spirit was hanging onto me.

I don't know why I was all light hearted and didn't took it as seriously as I should.

At first it seemed nice, it gave me great advices then I went further into asking it about their world.

I was aware that I was not really taking it seriously and was joking around and then the biggest possible regret came in.

I'm even shaking typing this.

I asked if they can do anything to hurt me and they said maybe and I asked how and they said strangle you and after they said that I don't know if it was my brain reaction but I started feeling a great pressure over my neck like I was choking.

I jumped out and told it goodbye and begged it to leave me alone. Beign an atheist myself I was so scared to the point that I started reading phrases from the Bible to chase away those spritis.

I don't know what motivated it or it wasn't that same spriti that did it but I cried and felt very sleepy like if I fell asleep I was going to die.

I have no idea if it's the brain that got into shock but I felt like a near heart attack could of made me killed.

I felt like I was slowly going to die and I just remembered that it told me that it can take lives and begged it to spare me.

I apologized so many times and despite my young age I could of easly pass out.

Now I feel slightly lighter but my neck still feels tight.

Does it mean that they are still eyeing on me or that it's my brain is playing games with me?

I'm scared to think about it. What if I attract it?

The best way right now is to not give them power and please if someone can help me deal with this situation, immediately tell me. As I had to break my pendulum.

If it's hanging onto me please tell me how to erase it.

I feel so weak and scared to sleep.

If any similar experiences please share.

Seeing my eyes now I can't recognize myself I got a scared stare hope I wasn't hallucinating.

Help me!
