I keep feeling like i'm in a dream or a coma like time is passing and i'm at a stand still and everything is moving fast what could it be?

See your doctor.: "Altered" sensation can be experienced with any number of ailments and should be thoroughly evaluated. Medication side effects are a common cause. This is often seen with migraines and some types of seizures. Brief moments of what we call dissociation can be seen with stress or emotional trauma. A doctor's visit is required to further evaluate these symptoms.
