The reaction of electrical devices and altered states of consciousness is certainly something that intrigues me. Can't say I've noticed this happening with DMT, but definitely with other psychedelics and in some cases focused meditation as well. I used to be in a long distance relationship.. other side of the world kind of long.. My girl and I would talk on the phone, and if we happened to be talking about something that was emotionally charging, lights and fans around us would flicker or intensify as our emotions peaked. This happened at both ends, and with a little experimentation, we found that we could influence these things at both ends. It started to get a little scary when we were apparently able to summon up gusts of wind outdoors around each other.. not the first time I've had this happen either. All in all, I've had enough first hand experience with this phenomenon to have figured out one of two things. Either my mind is, in these moments, synchronising with the universal flow to a point it appears to be actually affecting the physical reality, albeit subtley.. OR, the timing of such events is purely coincidental, and I'm only making the connection between mind and event because I want it to be there and am actively looking for it. I'm more inclined to believe the former, but also beginning to understand its probably more of a two way thing.. I and the "outside world" are not seperate things after all, so events like these are possibly just our way of perceiving a spike in the energy field (chi, holy spirit, ether) either locally or hyperlocally, and rather than purely being generated by the mind, we simply interpret and perceive the spike in this way. Anyways, I could rant for hours about stuff like this.. I hope that little snippet is helpful. Peace.
