telltale signs of an upcoming boss battle

[Sable Gear]

you walk into a big, empty, round room (first one that came to mind was the first boss in majora's mask)

very decorative door (most games that have dungeons)

and falling down a giant hole in the floor (legend of zelda majora's mask - fish boss)

Zelda is good for this one too: A simple puzzle-ish room with weak/medium difficulty enemies (often with a big door at one end).

A hall/passage of difficult traps followed by an empty room/hall (POP)

yeah those games do a good job of making you psych yourself out. ^^

with dead space, no one was allowed to play during the day. it had to be at night and all the lights had to be off. XP the apartment rules. though the rule ended up making it scarier for me too. :[
