Lucid dreaming is when people are aware that they are dreaming, during the dream. This awareness can also sometimes lead to the person controlling aspects of the dream.

While there is an idea that lucid dreaming can help with your mental health, or even during nightmares, it could also have negative side effects that you might not be aware of.

Popular methods of lucid dreaming often cause fragmented sleep as they require the dreamer to stay asleep for a few hours and wake themselves up for short intervals in between.

The Sleep Foundation found that these methods have a tendency to cause unhealthy patterns in the brain that can disrupt emotional regulation and memory consolidation.

Lucid dreaming has been shown to be beneficial to those who deal with PTSD, anxiety, and depression, but people who suffer from psychosis should stay away from this method.

Since people who suffer from psychosis have the most control over their dreams, lucid dreaming has been known to cause dissociation and even hysteria in their day-to-day life.
