Scary Optical Illusions are images where creepy things like skulls are hidden.
2 different things can be found in the same picture. You should see another image if you look at each illusion from distance and another one when you look just normally.
Happy Halloween :-)
Dr. Jekyll and Mr. Hide Scary Illusion
Step away from your computer screen. You should see the two faces swap over! This hybrid image was created by Phillippe G. Schyns and Aude Oliva of the University of Glasgow. It proves that we may not be seeing what's actually there, all the time.
Albert Einstein and Marylin Monroe
You probably see Albert Einstein on this picture. However, if you stand up and step 15 feet away, you will see Marilyn Monroe on the same picture.
