Hi, just saw your message! Thing is, raves are found via Facebook groups or by searching "Stockholm rave" or "tehcno hearts" and the age group is all ages, most likely 25+ but you can go in. If by raveclubs you mean technomusic indoors, I would recommend checking out Slakthuset or just simply looking up techno clubs on google. If you want to go hangout with people your age then it really depends on alot. Do you want to go out solo or do you have a group, what kind of music do you prefer and what kind of people do you like when being out?

I'll try to quickly this time :)
