Kellog Cornflake poisoning..?

I was sick for lat 2 days. I don't know if that was done by the food poisoning or the electronic harassment. 2 days ago, I ate cornflake for the easy quick supper. I know people eat it in morning rather at night. Um, that was just available in my kitchen and did not spend effort on cooking.

After eating it, I suddenly felt sleepy. I thought I might be tired and that was why I was sleepy, but I did not care. I woke up in the early morning and felt the need to throw up. I threw up quite much and then slept. My head was dizzy. It could be the cornflake, but I heard the electronic noise on my left ear when I pulled it to make the ear drum tight. It was a if something inside of my ear can make such noise like of the wiring near the speaker cause the hauling noise. Also, I could hear the high pitched tone but more like vibrating from 5cm above my right ear lobe. There was dull pain to my occipital robe. I had V2K as well insulting me while I was weak and so sick in my bed.

What makes food poisoning to happen? Will it make the person sleepy and later to vomit?

Ah, I attended the mass at Franciscan church 2 days ago. Nothing happened. No strange announcement.
