Possible bug hallucinations

So has anyone experienced bug hallucinations such as seeing a small roach on your arm? I have a really deep hatred and fear against any type of roaches and I saw one on my arm while I was under the influence of alcohol, though I’m not sure it was real or not as i did not feel it, I just saw it for a second and then nothing, hopefully I was just freaking out. First time this has happened, I just can’t tell whether it was real or not, I’m trying to convince myself it wasn’t. I heard bug hallucinations could be caused by stress as well which I have been experiencing, but then again it’s August and it’s still summer (worst season ever, argue with the wall) so I don’t know, I won’t say I won’t drink again since we all know the reason why that’s an infamous phrase. I guess I’m just seeking for reassurance if this has happened to anyone, comment under this post! 🙂
