Oneirogens

An oneirogen, is a substance or experience which enhances dream states. There are many suggested non-psychedelic plants, chemicals and experiences which are thought to induce an oneirogenic states. Those with the best scientific backing, include:

Plants

Plants contain a variety of chemicals which can work concurrently via the entourage effects. The main plants which are suspected of having oneirogenic properties include:

• Dream herb (Calea zacatechichi synonym. ternifolia) - traditionally used in Central America may be taken as a tea or smoked.
• African dream herb (Entada rheedii) - an African traditional medicine where the dried seeds are powdered and smoked in a pipe before sleeping.
• Mugwort (Artemisia vulgaris) - Thujone, the primary component of absinthe, is present in mugwort oil and in Korean tradition has been used in late night steam baths to encourage vivid dreams.
• Red Spider Lily (Lycoris radiata) contains Galantamine which has been shown to substantially increase the frequency of lucid dreams with a minimal side effect profile.

Dream Enhancement

There is very little scientific data on dream enhancement. One reason for this is during REM sleep, the skeletal muscles of the sleeping body are inhibited which makes it otherwise impossible for the dreamer to signal that they are in a lucid state. Although this has been known to malfunction in atypicals in the form of sleepwalking.

Simulation theory

There has been some recent scientific interest on the idea that REM dreams are a kind of a simulation of the real world on a higher cognitive level implies that dreaming could alter waking performance.
