Hallucinations different from illusions ?Yes hallucinations and illusions are two different things. Illusions array based on some real experiences.when we watch a movie it is series of multiple images but we can see the movie as if it is a single video. Another example of illusion is when we rotate a bright object in dark environment we can see a circle forming. But actually there is no circle in the air. Another example of illusion is seeing places water ponds in deserts. Actually they are the heat waves coming out from the sand which make it appear as if it is water. in all above examples we can see that there is actually something which is creating different image in the mind.
