Mushrooms, DXM, and MDMA...all totally different drugs, and I like them all for totally different reasons.
Mushrooms are just a beautiful experience, make me appreciate nature more than I usually do, and are good for more mellow, but slightly social settings. I like to talk to people when I'm on shrooms, but being around strangers is a little imtimidating. I love shrooming outside, too.
DXM I almost always do with just my boyfriend, at home. Not a social experience at all, very introspective, fun for watching movies or playing videogames, and for exploring our apartment in the dark.
MDMA just...feels amazing. It's the only "feel good" drug I like (I'm not even a fan of weed or alcohol). Good for social situations like parties and raves, obviously. Any place with cool lights and loud music. Or the beach. I love rolling at the beach.
