Abilify does have the side effect of "abnormal dreams". I would ask your pdoc if there's anything that can be done for that. We do dream as many as 8 or more times a night and anytime we sleep (I don't care for nap dreams, mine are usually about mixed up stuff from my actual morning or book I'm reading, etc.) so I don't know that the number of dreams can be affected but I've heard the intensity can be caused by meds.
