Marijuana and high levels of fatigue can both

cause hallucinations.

Explanation:

Depending on the sensitivity of the body and the amount of cannabis consumed, delusions and hallucinations may occur. Delusions are characterized by the "chase craze" that can lead to panic or mood swings. For example, a person enters a scene, sees a police officer, and wants to run away because he thinks the police are there to arrest him. Hallucination is seeing or hearing something that does not exist.

Hallucination can also occur in cases of extreme fatigue, which can cause various psychological and physical problems. Fatigue is characterized by a feeling of wear, tiredness and lack of energy. As might be expected, this is a fairly recurring symptom among many different types of diseases and conditions.
