Is proven that there is such an important process as detoxification of the brain in dreams, and this is a serious prevention of Alzheimer's and Parkinson's.
We often recommend our patients to intensify night detox using non-medicinal drugs. For example, such as MEGA NFC® medical 10. It is based on a zeolite (a microporous material of volcanic origin), which adsorbs and detoxifies heavy metals and itself completely eliminated from the body. As far as I know, the drug has recently appeared in Russia, Kraftway Clinic, and is also recommended for bedtime.
