So what is sensory deprivation? It’s the theory that when a person is deprived of sensory input, he/she will have hallucinations in order to fill that void. To test this theory, researchers placed test subjects in an anechoic room, a chamber made to block light and sound.
The subjects reported seeing faces, shapes, and having olfactory hallucinations. Some even reported feeling a threatening presence. Researchers explained that when we are deprived of sensory input, our mind gets confused and it creates its own. Not to worry though, this won’t happen often but when it does, just remember that it’s all in your head.
