IS LUCID DREAMING DANGEROUS?
Our lucid dreams are the reflection of our inner world and are not any more dangerous than our fantasies.
Of course, if you have any mental disorders, it is better to consult your doctor before you start learning to lucid dream (for example, lucid dreaming is not recommended for people who suffer from psychosis. See «Psychosis and the Control of Lucid Dreaming».)
Unless you have a mental illness, lucid dreaming is absolutely safe.
Thousands of people have been practicing lucid dreaming safely and many of them report that it has been a positive, rewarding experience, which enriched and enhanced their lives.
None of the numerous scientific experiments and studies of lucid dreaming has shown any evidence that lucid dreaming can be bad for you.
On the contrary, they have discovered and explored different ways how people can benefit from lucid dreaming.
