Is It Normal To See Things Like This?

I know some psychics can see certain things, and was wondering if it was normal to see things periodically. I don't see full figures that much anymore, but I still do see things. When I was younger, I would see full body apparitions and animals. I've seen things from a guy hanging from a tree, a soldier, a lady with black hair and a scarlet red dress, to something in a dark hooded cloak standing by a street corner. Things are less clear, but I still see things. What I mean by this is sometimes I don't see whole people. I don't know if it is normal, but I see pieces of them. How can I put this. It's like a flash of them, and then proof it disappears into thin air. I can usually see an outline or an article of clothing before it flashed into nothing. Then, I see the air kind of shimmer, and then it snaps away like it was never there. I can see shadows too, but they seem to last a little longer before disappearing. It occurs about a few times everyday. Is any of this normal? Can I do anything about it? I can't really talk to people about it without them looking at me like I'm crazy, and other sites do not really help. I was hoping this site could help me understand more about this. I really hope I'm not insane, and I can actually do something about this. Also, I know people post stories on here all the time, so if you actually took the time to read my stor... Thank you. I really hope you can respond, and help me shed some light on my little problem. So once again thank you for your time.
