Everybody looks for the good mood/fun weed, but I look for those strains that really makes you fucked up to the point you won't feel good. Anxiety, paranoia, irrational fears, feeling small in this universe etc.
I have yet not encountered such stuff.
No wonder you think you want it, you've never been in the hot seat!
I'm familiar with that feeling of thinking it sounds like some crazy fun... that was before I actually ended up in the midst of such mentally troubling experiences. It's not like watching a scary movie where you are outside the screen and can shut the movie off when things get scary.
I am not discouraging you from exploring, but do be careful. You might want to start with one small hit to get a taste of the feeling before you decide to take hugeass bonghits and go way down the rabbit hole.
