We do not currently have enough evidence to prove if they exist or don't. This means that until they are proven to exist or not exist, the only thing that makes them exist or not exist is your mind.

Since you used ghosts not ghost you are supposed to use "are" instead of "is". Therefore your question should say "Are there any ghosts in Santa Ana" or "Is there a ghost in Santa Ana" Regardless to answer your question, there is no educated evidence of a ghost existing anywhere in the world, including Santa Ana.
Not that I am aware of. But there could be if you believe in ghosts.
