It sounds like we've had some similar mind expansion experiences. I found that faith only works when I lean into it. Any amount of resistance can get in the way of the connection. Alcohol also shuts off the spiritual wifi.
The whole process for me was about suddender. Ultimately Buddhist concepts (releasing attachment, integrating shadow) are what caused me to open to Christ (during a deep psychedelic experience).
It's been a wild ride, but I'm infinitely grateful. The primary key I had to start with was Christ ≠ Christianity 🙏
