Which drug is known for causing dream-like states or trances?

PCP, or phencyclidine, is well-known for its ability to induce dream-like states or trances in users. This dissociative drug can significantly alter perceptions of reality, leading to experiences that feel surreal or disconnected from the physical body. Users may feel detached from their surroundings, which aligns with the trance-like experiences associated with its use.

On the other hand, cocaine is a powerful stimulant that increases energy and alertness but does not typically lead to altered states of consciousness reminiscent of dreams. Heroin, an opioid, primarily induces feelings of euphoria and sedation rather than dream-like states, and ecstasy, while it can cause altered sensory perceptions, is more recognized for enhancing emotional experiences and sensations but not necessarily for creating trance-like effects.
