How did you react when you first saw your hallucinations in the dark?

I don’t belong in this Reddit, I apologize. But I’m very interested in hearing from real people what their experience is like with hallucinations. Because I’ve had a taste of it from being too high. And I can only imagine what it would be like to see a hallucination, unexpectedly, in the middle of the night going to the bathroom. If this happens, how do you react? Have you ever screamed out of shock? Or fainted? Again I apologize if the questions are stupid or invasive. I just want to educate myself more on your experience. I respect what you guys go through.
