A strange hallucination in that one moment?

There was this one moment I always remember still today during my childhood.

It was from way back in grade school during one of my lectures in the classroom. I wasn't paying attention much, since it became a daily routine to slightly slack off during the season. I was seated in the front rows, somewhere near the teacher's table or in the middle columns? As the explanation began, my mind attention drifted off towards the doorway, seeing the hallway all covered with shadows or sunshine. It was then I experience that standstill?

No, it would be accurate to say, I was experiencing time dilation which I discovered years later in high school? The whole classroom had suddenly turned into a gray spectrum as the voices around me slurred into small incomprehensible noise. I believe I was breathing, and I was still there on that seat, but what made the whole situation weirder were the appearance of circular hazy-like projections in the direction I was facing.

They appeared in slight luminous mirages of white and it felt like there was a invisible arrow rotating inside them. They were like clocks, but closer to time stamps if you're visualizing. Why time stamps? There were fractions inside those circles. A numerator and denominator separate with a line you see in math. The numbers above and below were rapidly going up or down?

I couldn't register what exactly was happening until I tried focusing on them. To my surprise, the numbers went on faster than what I could read. I don't know why, but each clock appeared on the objects I was observing. The walls, the furniture, the blackboard; things like that. I like to say, perhaps even people? There was no logical explanation for my state of what I'm likely to be daydreaming, but it felt like that. I felt that, liked I somehow knew what those circles were attached to. The exact details? Unknown.

Hmm? I muttered mentally to myself. A strange experience it was, and bang! I returned back to the colorful noisy classroom. I could feel the wind again and my bodily posture. In that gray void, all I could do was observe and expand. It felt like minutes, but only few seconds pass by. I wonder what triggered such a weird daydream?

Sometimes I like to believe... maybe it wasn't a dream? That was no hallucination, it was something else entirely. Who knows? I still vaguely remember it to this day as I'm typing in it a blog. Even now and then, I recall it back inside my head, because sometimes I know things happening which I've yet to know. Precognition? That's a whole another story if I'm up for it.

Still kinda of scary a little. Imagine being forced to replay your whole life over and over on some television screen. I hate that. I detest such an eternity. I rather die for good and leave that immortal sarcophagus. Oops, I went off track again.
