 [ Symptoms ] i am 22 weeks pregnant and have a cold is it alright to take tylenol pm [ Disease ] severe psychological events can potentially cause hallucinations but i think it is rather uncommon for a panic attack to do so it would not be impossible however for you to have the panic attack first and the hallucination to begin afterwards it is possible that you simply noticed the visual disturbance before the physical sensation of being afraid and that coming down from the panic left you physically or emotionally tired i would recommend that you tell someone if this happens again since a lot of other things can cause hallucinations it is possible that this was an isolated incident but it never hurts to be sure <positive_smiley>
