[/INST] As ct brain is normal, nothing serious. You may have positional vertigo, which occurs with change of posture. You get once you come out of bed from supinr position. You first turn to lateral position and then slowly come out of the bed, symptoms will go gradually. Moreover rule out cervical spine problem too. </s>
