I would agree that you would have to have sight at some point in your life to have "hallucinations".

But you would still "see" something if you had never had sight.

It may be the best way to show color to the blind.
justanotheramerican Reviewed by justanotheramerican on . Hallucinations I was just sitting here wondering do blind people hallucinate when doing acid ??? or do they mentally visualize as i am sure that a hallucination would require you to see your surroundings in order for you to see them morphing or shape changing and the like...well do they or not :confused: Rating: 5
