Head & body separation uncontrollable tickling

Description: I do a head and body separation spell that backfires on me. a very strange side effect, i can feel my body, but i cannot move it, in fact, it seems to have developed a mind of its own. my very own body is no longer under my control. it begins to feel itself up and tickle. my feet and sides no matter how much i protest there’s nothing i can do. i wonder how long this spell will last.
