What could this reoccuring dream mean?

in the dream i am doing some kind of drug that is liquid and yellowish-clear, that i shoot up in a needle. ive had this dream 3-5 times in the past 3 weeks. the first one started out with this guy with a goatee showing me the drugs and how to do it(but no words were said), it looked like he was looking down on me like he was really high up or tall or something, then i used the drugs, and every dream now i just use the drugs then wake up.
