HALLUCINATIONS---------just for fun have a look at this video

A hallucination is something that someone experiences which is not really there. 

Probably the best way to describe a hallucination is that it is like dreaming while you are awake. Not daydreaming, which comes from conscious thoughts, but the things contained in your sub-conscious which are projected from your mind and appear to blend in with the real world. Hallucinations can be quite deceiving (especially if it is a mix of a visual images, sound and even the sensation of touch) and, like dreams, sometimes you know it’s not real but other times you are unsure. Also like dreams, hallucinating can warp or distort your thinking, causing you to know things you shouldn’t and to completely forget things that are common sense, obvious and every day practice. 

There are five different types of hallucination: 
* visual (seeing things) 
* auditory (hearing things) 
* olfactory (smelling things) 
* gustatory (tasting things) 
* tactile (feeling things) 
Often, two or more of these will be mixed together at the same time...
