Hallucinogens.
Hallucinogens are a diverse group of drugs that alter a person’s awareness of their surroundings as well as their own thoughts and feelings. They are commonly split into two categories: classic hallucinogens (such as LSD) and dissociative drugs (such as PCP).

Additionally, dissociative drugs can cause users to feel out of control or disconnected from their body and environment.
