so say i wanted to have sex, would it feel real? both the sex and the drug? can you engineer drugs in dreams? like made up drugs?

could i say mix 2 of my fav drugs into 1 super drug and do it in-dream?

would the sex in the dream make me feel like its real? would i wakeup with a mess down below? lol


Could i theoretically goto other planets? leave the earth? fly around the universe? would my dream self suffocate outside the atmosphere?
