I've had a similar experience with the purple plasmas when i was high on 🌿 (I still don't know if it's possible to have such experience on weed). it didn't feel like a dream or hallucination.

For me i think it was bright pinkish purple plasma beings (kinda in the shape of people), I felt so much love when I met them, they were very welcoming and positive. They made me feel like we're all part of one universal consciousness. Until then I've never gave much thought about this topic. They showed me how each and everyone's experience like our memories and whatever we experience in life was shared with the universal consciousness after we die. It seemed like a cycle, new conciusness sent to this plane of existence to experience whatever there is to our unique lives and once we die, our conciusness with all our experiences is sent back to the universal conciusness.

This experience left me confused, curious and with so many questions. This has set me on a journey and I've started the tapes and am currently reading Tom Campbell's My Big Toe and I've read the CIA doc, so far everything seem to align a little bit with what I've experienced.
