Hell yes, always.
There’s this one I had from when I was eight years old: in the daydream, my elementary school caught fire. I had a friend on crutches. Her crutches were across the room, for whatever reason, so I carried her out of the burning school on my back. I was interviewed by local news channels, and they put up a plaque at my school in my honor.
I thought about this one so so much that I sometimes forget that it didn’t happen. I know every detail as if it were a real memory.
As for now, the grandeur is just the totally toned, tan, proportionally perfect body I don’t have :)
