Austin D. asks Dear Blocko, Why Do Some Drugs Cause Intense Dreams?

Intense dreams that we can easily remember when we wake up, also known as vivid dreams, are caused by a number of different factors, including certain medications., These include beta-blockers used to reduce blood pressure, drugs for conditions like Parkinson's disease, and antidepressants.

Scientists believe these medications are able to affect dreams because of their influence on the sleep cycle, specifically the REM stage, which is when dreams are most vivid.

Drugs like beta-blockers--which are responsible for one-third of nightmares reported during clinical trials--and antidepressants suppress REM sleep., , While it may seem like this would result in less intense dreams, scientists believe, from studying the effects of antidepressants, that they actually just delay REM sleep until later in the night.
