Why don't you have taste hallucinations?
I had a client yesterday who told me that she cannot go to sleep without a radio playing or the TV on. This is a common behavior. Many people use music to drown out the sound of the voices in their head. Or more correctly, the feelings that they experience as if there were voices in their head.
And that got me thinking. Hearing sounds, words, or voices is very common. Visual hallucinations, seeing things or people who aren't there is the most common. They are not necessarily an indicator of a serious mental condition.
But I have never come across an Oral hallucination. Why do people not get hallucinations of having a taste of banana in their mouth? Or curry, or any other taste? If the mind can produce the other types of hallucinations why not the taste one? In dreams we think we see and hear things, but I personally have never had a dream where I tasted something.
There is a condition called synesthesia where colors are experienced as smells, and noises as tastes. The various sensory pathways get switched over, but that is not really a hallucination. Tinnitus is an imagined roaring in your ears, but that also is not really a hallucination.
People with schizophrenia sometimes believe that they have an unpleasant smell in their nose, or a bad taste in their mouth. It seems never to be an actual food or a specific smell. These types of taste hallucinations are clearly associated with mental illness.
Can you hallucinate a strawberry?
I wonder if there has been any attempt to hypnotize people to experience tastes and smells? When stage hypnotists persuade people to eat an onion, is the subject just ignoring the taste of the onion? Could the hypnotist persuade the eater that the onion actually tastes of strawberry?
I personally can vividly picture a strawberry. I suppose I could imagine the sound of the food processor making a strawberry smoothie. But I cannot summon up a memory of what a strawberry smoothie tastes like. I recognize the taste, but I cannot recall it in advance.
Can other people summon up tastes on demand?
