I used to "daydream" a lot. When I would "daydream" I would no longerr see or hear or smell, but I would follow these strange patterns in my mind, always going deeper and seeking and end but never finding one. After about 20-30 minutes, I would always reach a strange point where my mind could not go any further, but I knew there was something beyond the point I had reached.
There were no clear directions, it was a very strange experience. I can't attribute it to a dimension and I did 2 years of University Math. I wish I knew what it was.
They became less frequent as I grew older and I had my last experience at 16. Nowadays, I feel like it has translated in me viewing the infinite of the patterns in this world. It's kind of more than that though, and still I cannot explain it. It makes me not want to speak because everything I say, even in this explanation, is incorrect because these words I'm using do not accurately express the thought, emotion, and experience involved at all.
Thanks for sharing, I think it's very interesting. Don't give up on explaining it though. I'm sure with time and effort you will find a way and/or the words to explain it. If we all spoke more about how we perceive the world, we all would have better words for it, and a better understanding of everything.
They are surprisingly hard to grow like that believe it or not. That's approximately a 1 in 50 occurrence and the good ones command a high value. I tried for about 5 years to grow one like that unsuccessfully. Various conversations on the Internet resulted in giving up and returning to a more valuable carb-heavy crop (potatoes).
