Vertigo while laying down?

Hi, I just started Abilify, 5mg. I took it on Thursday and accidentally missed yesterday and then took today's dose. I get this odd feeling when I lie down or move too quickly while laying down that feels like I'm moving more than I am?? If that makes sense?? That's the best way I can describe it, like if I move too quickly I feel like I'm rocking side to side. Common side effect, I take it?
