Olfactory hallucinations involve smelling something that doesn’t have a physical source.In this instance, you might feel the imagined sensation of bugs crawling under your skin, or a person's hands on your body. Tactile hallucinations are feeling sensations or movement on your body.For example, this might include seeing someone who's not really in the room, or seeing flashing lights that aren't actually there. This ranges from people, patterns, lights, or other objects. Visual hallucinations happen when a person sees something that isn’t real.

The sounds can be anything from footsteps to music or tapping. The voices can be positive, negative, or neutral, and sometimes, they command someone to do something. This could include hearing a voice speak to you, or experiencing a distorted sound.
