Non-Chemical Hallucination

There are many interesting ways people have created hallucinations without hallucinogens or any other chemicals. After dreaming (obviously), the most common way to hallucinate is by using light. Lights blinking at certain frequencies can cause vivid hallucinations by activating your pineal gland that equal the intensity of psychedelic drugs. There are even glasses that are made so you can experience this anytime you want but it is probably not very healthy for your eyes. Next is sleep deprivation. This one is quite common especially for those who stay up late at night or those who haven’t gotten enough sleep. After a couple days without proper rest you start seeing weird colors and hearing odd things. The longer you do not sleep the more vivid

Unlike a sauna in which you only spend around 20 minutes, Native Americans spent hours inside sweat lodges. It was to cleanse the person and increase his/her adaptability to heat. An odd way I have been looking into is sensory deprivation. In theory to cause a non-chemical hallucination you have to push the sense to its limit. This is the other extreme. Scientists have come up with a room called the anechoic chamber. Its walls are made from RAM (Radiation absorbent material) arranged in an interesting pattern so that the sound is trapped and echoes forever inside the wall. This leaves the room itself devoid of any sounds that do not come directly from the source. In the experiment the subject is completely deprived of both sight (the room is dark) and sound, the two most important senses. The first couple of minutes the subject feels at ease but as time goes on the person starts feeling uneasy. Soon after the subject starts hearing and feeling the heart pumping blood to their brain and blood going to the person’s extremities because of sensory adaptation. After that most subjects feel sick like they are about to throw up. It’s after around 45 minutes that the hallucinations
