(sorry for my bad english)
i am a 18 years old athiest who lives in mostly muslim country.

When i was 16 years old i had depression and my parents thought that i might have a demonic possession so they called a chick to come clean our home and exorcises me.

The chikh came and started cleansing the house by spraying holy water everywhere and reading the quran loudly , after he finished he asked me to lay down on my bad and started screaming the ruqya in my ear and hitting my belly repeatedly (ruqya is reading certain verse of the quran against things like evil eye or jinn possession) , after a few minutes of that ( i nearly became deaf) he stopped and told me what i saw when i closed my eyes , i lied and told him that i saw two eyes hovering over me when i closed them ( just to see what he would do) he got some water , read the quran over it , put it in a water spray and told me to close my eyes and spray wherever i saw the eyes , and so i started spraying randomly and suddenly my mother started screeming from the other room , when we got there she was spazzing and screaming hysterically after that she started attacking the chihk screaming " get him away from me" " go away" the chihk advised us to get her to a clenique that treats demonic possessions with roqya

We took her there and she acted just like the girl in this video https://www.youtube.com/watch?v=50zfoDL0IKk .

When someone very religious that believes in demons and angels and other fairy tales and gets exorcised there is a psychological explanation to what happens to them if they start having seizures and hysteria but my mother isn't very religious ( she doesn't even pray five times a day) and she wasn't the subject of the exorcism that day I was.

What am asking is a logical explanation to what happend.
