I rarely have bad trips. I'd guess in terms of ratio I end up with about 1 out of 10 being "bad" although it's hard to define it. I've never found myself being chased by monsters, felt any pain, or saw any hellish scenes of gore... they're usually just characterized by overthinking things that are going on in my life, leading me to be really depressed for a few hours. However, I think of my "bad" trips just like I think of winter. Although they can be pretty lame, they help me acquire an even greater appreciation of any state of not having a bad trip -- i.e. being sober, having a good trip, or any other state of mind (just as I loathe winter, but it makes me appreciate the other seasons all the more). Also, so far there's always been something I learn (about myself, other people, life in general, etc) from every trip, good or bad. So, I'd say there's technically no such thing as a bad trip. I'll just call the phenomena "temporarily unpleasant" trips...
I hope I'm making sense.
