Just want point out that our bodies naturally produce DMT from the pineal gland when you connect with your 3rd EYE and in order to do that you have to be in balance so there is no need to worry about a bad trip.
Here is a blurb about DMT
What is DMT and how is DMT made within us?
DMT (dimethyltryptamine) is made from our pineal gland, a small pine cone shaped gland that is located in the very center of our brains, and it is the most powerful naturally occurring psychedelic compound. DMT is present if not in all plants and animals most of them, and is a vital molecule for existing on this plain of reality as it helps give color to our lives and happiness of mood. Some report DMT to be also made and present within the human spinal cord, which may have to do with claustrum oil secreted from the brain and how it interacts with the pineal gland. Our brain will naturally make DMT, but so do other animals as well. When humans are in heavy REM sleep delta stage 5, the brain changes wavelengths to a trance like state where DMT is administered before repeating a 90 minute cycles between each stage of REM sleep. DMT is released during the deepest of sleep and is the responsible for dreams as well as healing of the human body, making DMT a vital endorphin and the reason proper rest is more than just getting some sleep. Only during heavy sleep can we receive DMT at an unconscious level, but meditation isn’t exactly sleeping and we can still experience our own DMT while conscious.
