Can CBD oil help to prevent nightmares?

The endogenous cannabinoid system (ECS) is a complex network of cannabinoid receptors in the peripheral and central nervous system. Research suggests that it can help to decrease insomnia and lower anxiety leading to fewer nightmares. However, cannabinoids can also have the side effect of causing nightmares. The research is conflicting as to whether or not CBD oil should be used before sleep. Some doses appear to be activating rather than sedating which could lead to more vivid dreams and in some cases nightmares. There are better natural preparations to reduce nightmares.
