PAREIDOLIA:
Your mind is actually programmed to see patterns in chaos. Meaning when you see something in an orb, tree, or window it could be just a case of Pareidolia. The first thing our mind happens to be programed to see is ....a face. That's right - so when you are looking over those photos, try to make sure that it's not your eyes playing tricks on you.
AUDIO PAREIDOLIA:
Audio Paridolia is the auditory form of Pareidolia. It's when your mind is desperately tring to grasp words out of sounds you're hearing. Don't believe me? Listen to a song in a language you don't understand. You will swear you hear some words in your native language because your mind is trying to make sense of it.
