The poster you replied to specifically said he had no way of finding words to explain his experience. This is common with LSD trips and other such experiences. The very first line in the Tao Te Ching is "The Tao that can be spoken is not the eternal Tao." Some things are ineffable. For instance, it's not possible to explain the experience of the color red to a blind person. You can explain metadata like the fact that it is light of a certain frequency, but there is no way to actually convey the experience.
> Reality includes the past and the future though. This just sounds myopic.
The future and past may or may not exist as physical realities, but that's not relevant to the direct human experience. Unless your brain has time travel capabilities, your experience of the past is just replaying memories and the future is just simulations of potential paths. There is only what is happening right now - future and past are just fafuture. That doesn't mean you can't think about the past and future and make decisions based on those thoughts, but it is impossible to experience the past and future
