"Even though I was legitimately scared, I knew it was all in my head."

That's just it, though. You knew there was no danger, right? So it didn't matter if you made the stupid decision, right?

It's different when a character in a genuinely dangerous situation (lost in an alien spacecraft beyond human understanding, possible alien lifeforms on board) does something stupid for the sake of advancing the plot (gets high, pets the first alien he meets).

Horror movie characters don't act realistically.
