Although I am not suffering from bunny-on-the-head I do have baby-squirrel-on-the-shoulder at the moment.

Bunny on the head was sorta suffered when you had possession of the bunny.
Symptoms were confusion, hair pulling, and the strangest sensation of a foot tapping on one’s head.
Squirrel on the shoulder may be vastly worse, as there is no symptom database yet.
