How do i know i was not God?

Hey everyone

Before one year i took 800 micrograms of Acid. It was the 4th time.

So in short version I took the Acid and after one hour i began to feel bad and knew i took too much. After that a geometrical world builted in front of my eyes and then my vision became black.

It was not longer than 15 seconds.

I forgot that I was a human. I thought I was dead and a soul stuck in another dimension forever. It felt like a nightmare.

After that i stood up and panicked, but i knew who i was. The rest of the time the effects of the drug diminished.

How do i know now, that i maybe wasn‘t God in that time of blackness? (from a monotheistic view, not buddhistic)

I wanna just make sense what happened in a metaphysical view.
