I was just thinking that dreams are highly stimulant, and this may be one way to ascertain if in a dream (or a simulation?) or in the real world. Real world always has sporadic lulls.

Tell me if I'm wrong now , but I've heard that the "why" we dream , is harder to explain than the "how" we dream.
There are all sorts of theories about why , as you probably know , some are spiritual , some are more pragmatic, but one of the theories that always made the most sense to me , was that it was some sort of simulation , as you say , but a way of simulating a dangerous scenario that could potentially happen in real life , and that inside of this simulation , you brain sort of "war games" out these scenarios , and documents the results , so that if something were to happen in the real world , your brain would have already populated itself with data on how things might go , and what to do .
Well, I have dreams of places, before going there. I was amazed when discovered that I have dreamt of the place couple of days before.
The weirdest thing i ever dreamed of before properly learning it was a time i was very young. There was this group of old people yelling at me and a goat nearby. I was holding a long blade like a machete and they kept saying "sever the head". I think i was about 6 when this happened and I didnt know what sever meant but must have overheard it contextually at some point. I took the blade and managed to lop off the goats head. There was dark brown blood gushing out. Then i saw a willow tree and woke up.
