This is inappropriate. I asked you a question. In order to answer your question, you have to answer mine first. We are not mind readers here. If you want someone like that, contact the Psychic Network!
If you want temporary amnesia (not amnishia), you will have to have severe blunt force trauma to the head. When and if that happens, it is possible that you could become permanently brain damaged as well.
