When I was under severe stress as a teenager I had an episode where I thought god was talking to me and wanted me to become a nun. It was night time and I told my father to take me to the church so I could speak to the priest there. He didn't take me.

Another time I was sure that a boy I knew drugged me somehow by holding my hand and I was afraid I was on acid or something. I had to sit out of the dance class and calm down. A nurse I danced with gave me a neck/shoulder massage and told me I shouldn't be under this much stress at my age. Both times I was under severe stress and both times as a teenager.

It hasn't happened since.
