These sensations are true vertigo and are generally associated with physiological and pathological stimulation of the vestibular system.

It can be a mild feeling of unsteadiness, floating, or slight movement, and can be caused by dysfunction of the vestibular system or by disorders such as hypotension, cerebral ischemia, hypoglycemia, or anxiety.
