Making monster disappear

[membrain]

Hi there,

I'm still playing Amnesia but there were several situations where I accidantly made the monsters disappear. Don't know if this is meant to work like that.

I did it just by sneaking through the dark, waiting for the next time a monster appears. I ran somewhere, jumped on a box or a table where the monster couldn't reach me and waited for it to disappear. Sometimes I even sat directly near a lit candle and the monster didn't see me. After a while lurking around the monster went outside the room (or wherever I was) and about half a minute later I went after it but it was ... gone?! I could make noises, throw things around and run around the place but most times the monster didn't reappear.
Did this happen to you, too or is it a glitch or what? I'm a bit confused because if I just had to wait for the monster to disappear and then continue playing it would really take much of that creepy atmosphere. :\
