There was one time when I was in kindergarten, and I had no friends at the time, didn't know anyone, and was close to tears on the playground. Without warning a girl sat down next to me, and I don't even remember what she looked like except that she had red hair and that she seemed to glow. I felt as though I could tell her anything and she would never judge me.
I told her what was wrong, and she told me something, but try as I might, I can never remember what it was she said. All I know is that she helped me and inspired me. I remember running off, and having a strong feeling to look back. I did and the girl was gone. I promised myself that I'd never forget, but as soon as I got home, I started to forget her. What she looked like, what her voice sounded like, what she said to me, everything. I think that there were others there, waiting for her.
Recently, I've been trying out automatic writing, and the first time I tired it, it worked. The person didn't want to talk, and after they said that, there was a loud breathing noise. After that, they said, "Leave us alone."
I've also been having weird dreams lately. One time I dreamed about my grandmother, but the weird thing was that she was just a head. A few years later, she died by a blood clot in her throat. That was around the same time when I was having strong déjà vu. And I've been seeing orbs and red dots in my dreams as well. I don't know what to think, and since I'm still learning, can someone help me find the answers?
As far as the convulsions, it may be an extreme reaction to precognitive feelings. If I sense something is going to happen, it can make me really sick and cause me anxiety attacks. Speaking in tongues may be related to the language barrier, if there is one.
Maybe try sharing the images you draw when you are influenced by the spirits around you, here. If you feel comfortable doing so, that is. You never know who will have fresh insight for you!
I hope that any of this was helpful! I wish I could give you more affirmative answers
