The capacity for the mind to make up imaginary stimulus is infinite, one need only think of this ability during masturbation and realise, yes, imagination can effect the body so much there is a physical response. Think of nightmares and response to a tap on the shoulder in the middle of the night. This can make a person’s heart rate so high they jump. But that feeling is soon replaced with relief and embarrassment at reacting in such a way, just as the belief system a person thinks of during masturbation, is soon gone after they have orgasmed. This is also true of actors when they are performing, the better they are at acting, the more likely they are to have a physical response, that is they can blush or cry within the scene, because of the imaginary stimulate.
During times of psychosis the mind does not let go of the belief system, it effectively becomes hypnotised into believing an imaginary stimulate is real. The mind during psychosis takes a step further than a method actor would and becomes a hundred per cent swamped by imaginary feelings, like most people do when they are dreaming.
If you have the capacity to believe in succubi, then during a psychotic episode you could actually feel like you were having sex with one or two or however many apparitions that appear and give the tactile and maybe also visual and auditory hallucinations. It would likely be a terrifying experience, heart beat would be up as the person feels the intercourse happening. It seems absolutely real to the person and in a way it is real and it isn’t. It’s real because it happens while the person is awake and there is no way of waking up from the horrifying trance state they are in. But it could mistakenly be seen as wish fulfilment when it is more likely to be some sort of sense memory of the past when the person had a horrifying sexual encounter.
Sense memory is an acting tool, most often used in film. It requires an actor to think of a time when they tasted an orange and for that actor to then think of the taste of an orange during a scene between their character and other actors. Sense memory isn’t real, the actor doesn’t bite into an orange, just has that sweet taste their to give their mouth a certain expression during the scene. If the sense memory is imaginary, like walking on cotton clouds or using a drug the actor has never tried, then it requires more research and imagination. A scene might require the person’s head to flip like pages of a book and an animation gets added later on. This would require a person to imagine that is happening. The actor may or may not feel it, depending how deep their trance state is, where as a person having a psychotic episode does feel it.
Often there is no reason for these tactile hallucinations happening, or the reasons are hard to find. Sometimes dehydration can cause prickling in sensitive areas that get seen as some kind of attack on the body during a psychotic episode. Usually, the reason for tactile hallucinations existing is the same reason as why some dreams are prominent and other are not, something disturbing has happened that hasn’t been sorted out yet and the mind is trying to find a way to remedy the problem.
Reasons why some people can be hypnotised and others cannot is the key to why some actors are good and some actors get too much into the scene they bump into the lighting equipment and furniture. Self and group hypnosis is the key to developing sense memory for an acting scene, it’s also the key to most religions. Belief in something however that no one else belief in and isn’t your job to believe in, is psychosis and how best to break the hypnosis a person has got into is debateable. Most common technique is tranquilisers and hospitalisation, but that has side-effects that are so bad that they wreck the person’s quality of life. There must be another way, perhaps it may be found in acting techniques that a person uses to shake themselves out of the character they have hypnotised themselves into being. How can a psychotic episode become as short lived as masturbation instead of extending out into weeks and months of belief in something that isn’t real.
