I have visual hallucinations?

I'm 18, female, and I've been hallucinating pretty regularly for as long as I can remember (like... preschool). I've never been on any drugs. It's everything from insects to plants where plants obviously can't grow to people just standing there to ridiculous things like Easter Island heads speaking foreign languages. It's only rarely ever been "scary" or "malicious", and I can always tell that it's not reality and consciously ignore it. Schizophrenia does run in my family, but, as this has never ever caused any of the "social" symptoms of schizophrenia, could that still be it? Should I go to a psychiatrist even though this hasn't ever really caused me any real functional problems in life?
