Sometimes delusions can create different types of hallucinations. Often people who believe others are trying to poison them may notice a funny taste to their food. This can be especially frightening because it seems like solid physical evidence.

I'm sorry you had a bad experience at the art show. It seems like the stress of the event caused you to become delusional. Do you have a pdoc or therapist you can talk to about this?

Also, there will be other art shows!

Do you have any photos or digital reproductions of your art to show us? I'm sure you would get many positive comments.
