Need Advice

I met someone online that claimed they could help me with my depression with hypnosis. I agreed to sessions while in bed and also while sleeping.

At first the sessions were them just learning about my past, and they helped me greatly with my depression. They seemed to learn so much about me very quickly, and many of the things they learned about me I didn't even remember myself until we discussed them.

Now I am having a problem with them harassing's me through out the day. I do not understand how they are doing it, and can not find any proof either.

I believe they may be some type of hackers. They are some how able to talk to me through out the day, but other people that are in the same room as me are not able to hear them. When they talk to me, it sounds like I might be reading something in my head, like my internal voice.

I was wondering if anyone knows of any type of hypnotherapy that is used where the one hypnotizing the patient is able to speak to someone but make it sound like the persons own thoughts. I'm having trouble finding anything related to this with hypnotherapy while sleeping, which is when most of my sessions were performed.

Appreciate any help and guidance you may have.
