When people ask why the pineal gland causes visions, we need to separate the biology from the mysticism. Scientifically, the pineal gland produces melatonin to regulate circadian rhythms. When it activates—usually as daylight fades—our brain shifts from beta to alpha, then theta waves. This is the hypnagogic state. Psychologically, this is when the conscious mind’s "filter" drops, allowing the subconscious to project images, memories, or archetypal symbols. Carl Jung called this "active imagination." It’s not the gland literally opening a portal; it’s the neurochemical trigger for the psyche’s theater.

In Tarot, this dynamic maps perfectly to The Moon card. The Moon doesn’t promise literal otherworldly travel; it symbolizes intuition, the unconscious, and those eerie, dreamlike visions that feel hyper-real but require careful interpretation. It’s about navigating the murky waters of the psyche without losing your grip on reality.

I’ll be blunt: I’m exhausted by New Age vendors slapping "pineal DMT portal" stickers on crystals and incense. The pineal gland doesn’t spontaneously combust into a dimensional gateway. But the visions themselves are valid psychological events. They’re often the mind’s way of processing stress, trauma, or deep intuition. If you’re chasing these states, look at your sleep hygiene, manage your cortisol, and perhaps meditate on The Moon’s symbolism to ground the experience. The pineal gland is just the biological switch; the visions are your subconscious speaking.

Has anyone else here noticed how sleep deprivation or high stress alters these visions? Or is it mostly a calm, meditative practice for you? I’d love to compare notes. Berlin’s long winter nights definitely amplify the theta-state experiences for me.
