Can you tell me, are minor but frequent hallucinations normal?

Yes/NO: Hallucinations can be both Physiologic like the ones right before falling asleep ( Hypnogogic) and the ones as you wake up (Hypnopompic) or they can be abnormal , usually people who suffer from abnormal hallucination lack the insight (because of mental illness) hallucinations get worse with stress and anxiety . can be a side effect to medications as well.
