Calea is not familiar to most people, but it is widely used in Mexico, where it is called “the dream herb”, and is used to promote dreams of divination.
In clinical trials, Calea has been proven to increase the duration of REM, or dreaming, sleep. Calea creates an interesting sleep pattern, in which users report quick onset of deep sleep with many dreams, followed by immediate awakening after the dreams.
Coming out of sleep right after the dream often helps with dream recall, rather than sleeping on until morning and losing the dream’s details. For greater lucidity and control, try Calea with Wild Red Asparagus.
