Just a flashback... (spoiler)

[darkpast]

The first time I entered the water monster area, I didn't budge when I saw the splashes coming towards me. The reason? I thought it was just a flashback or scare event, so I just idly stood there (I thought it was impossible to escape) while it *chomped* me. When I survived the first hit I thought wait... what if it *chomp*... oh shit, gotta reach those *chomp*...

"Stay out of the water..."

This is the first time a game actually managed to do this to me. I feel rather embarrassed now, but at the time I was just totally immersed and convinced the level could not just have randomly flooded.

Did anyone else have a similar experience?
