The dream, in which you took the cocaine, shows your state of mind, where you feel useless and exhausted. Perhaps you are trying to get out of your duties and dedications. You have no arrogance or pride and would do anything to get out of the life you are living at the moment. Alternatively, the dream may suggest you to have more fun and try to relax a bit in order to get satisfaction.

Dreaming of wheels or pulleys (of any kind) spinning really fast, means that youre very active, maybe a bit of a nervous person, and a hard worker, which portends that youll have success in your activities. However, if you dream of wheels or pulleys that are not moving, are broken or old, then it means the opposite.
Dreaming that you hear the melancholic notes of a harp, indicates some things, that you have been enjoying (business, entertainment, pleasure, trips or just good luck), are coming to an end. Dreaming of a broken harp indicates the end of joy, for example, between lovers, perhaps a painful and difficult illness, either of your own or of family member; it may also mean making some mistakes in your political or social relationships. Dreaming of playing a harp indicates that the dreamer is overrated, so he should be a bit more humble, since that can lead to serious failures and frustrations.
