The person who wrote what I'm going to link you is clearly mentally ill, and it's hosted on a conspiracy theory wiki. I hope linking it doesn't get me flagged as a spammer or nut. You can take the author at face value in regards to them actually having gone through what they're describing, I'm 50/50 split on that.
Despite that, I think it's interesting stuff to read about, basically the adult version of ghost stories. It's what initially made me make the connection between MKUltra (as explained by those who believe in it) and splitting/disassociation.
It's really long and rambling, and I don't blame you if you end up deciding not to read through it.
