We vibrate
I was just outside basking in the wind, enjoying the sun, when I noticed a fly on the side of my house. I was just looking at it move around and of course its movements appeared jerky, like it was jumping around. Then it just hit me, for whatever reason, it's just moving faster than my eyes can perceive. I've known that before but the new realization is what came next. If it's moving faster than my eyes can perceive then my eyes are operating at a certain frequency. They're sampling time at a certain rate; slower than the fly moves so I perceive jerky movement from the fly.
It's somewhat a bit of a stretch to extend from that to say that my whole body is operating at a certain frequency but, it seems so true. Every cell in my body operates at a certain rate. Not unlike how a photon oscillates at a certain rate. At the very least the cells that make up my eyes operate at a certain rate.
That definitely makes the question of what is time an interesting one. Time would just be a construct our minds create when it fuses together the discrete sensory moments it captures. Hmm, I know what I'm saying now has already been observed by others but it's always a unique thing when a light bulb goes off in your head and you recognize a novel aspect of reality.
The larger principle that got me excited though was the statement from spiritual sources I frequent that we blink into and out of reality. That we don't entirely exist in this dimension. Seeing that fly move faster than I could perceive made that statement seem much more relevant and true.
