I think other than a few people too, most people who have experiences don't WANT to be able to prove they're real.  Because if they are real, and someone like you would say they're real?  While other people would no longer think you needed a straight jacket (a good thing), you'd still have this "little" problem of having unwanted ___________ invading your privacy, your personal space, your life.  Trust me, it's easier thinking (hoping) that you just have an active imagination...
		
		
	 
What a second.  What?  I thought you said it WAS real.  Whether or not you get something on tape you're still going to be dealing with it, no?  I'm in the Kubick camp that horror movies are uplifting as they would be evidence of something beyond death.  If you really see plates flying off shelves and crashing into walls and cats flying around the joint, time to celebrate I say.
		
 
		
	 
I'll share another little story.  Absolutely nothing supernatural, but maybe you'll get the point.  When my oldest was about two, our family room was at the top of our second floor stairs (now her bedroom).  Other than some of the experiences I have mentioned, nothing "natural" happened in the home that was out of the ordinary.  One evening I was sitting on the couch typing away on my laptop, when I saw a shadow outside the door to the family room.  I looked up, and after about a second, I saw this huge bat fly around the corner (up the last few stairs), toward the family room, then turn around and fly back down the stairs.I thought "holy CRAP!" and got up and shut the door to the stairs.  I then tried not to think about it, and didn't tell my wife...as the For Sale sign would have been out the next morning.  Weeks went by and nothing unusual happened.  So after a while, I stopped thinking about it.  Water under the bridge.  Then one night, I went downstairs around 10pm to get a snack, when I got "buzzed" by a bat that was flying between the dining room and living room.  I immediately thought about that night in the family room, then did what I needed to do to capture and get that bat out of our home.  That was about 6-7 years and about 8-9 bats ago.   
 
My point?  That night in the family room, I saw a bat.  I had never had an experience with one before, and it scared me.  However, after shutting the door, and having several days pass, I started trying to talk myself into the idea that it might have been my imagination, or I might have thought I saw something that was just a big bug or ??? casting a shadow just right via it's position next to a hallway light, or ???  Thing is, I knew what I saw.  Only I tried to trick myself into believing otherwise.
That's what I was getting at.  If you see something you "know" can't be real/there (ghost, demon, ???), you'll look for any and every opportunity to have your world view/order preserved or restored.  Because life is 1000% easier that way.  It's when your beliefs and your world view/order is smashed into about 1,000 pieces that life gets hard.  Also see: what would happen to Hoart Petterson if he had an experience that he could not easily explain away.  Explanations that he knows aren't just trying to convince himself that he didn't just see a bat fly up the stairs, anyway.
