Explanation:

Flashback is a general term used to describe the phenomena of experiencing or remembering same events after some time. People who take LSD can experience flashbacks. Sometimes they feel they consumed the drug when in reality they did not and will experience the same effects again. They can even re experience the euphoria which is the extreme state of ecstasy. They can also experience the bad effects. If the flashbacks persist, it can lead to a disorder called as Hallucinogen Persisting Perception Disorder
