If you dreamed of a drill, and in a dream you really feel its vibration, in reality you are very seriously disturbed, and, this is a circumstance that you can not influence in any way. If, in a dream, the sound of the drill acts on you depressingly, irritably, then in reality you are fed up with small things, worries, problems that take away the lion's share of time and do not bring adequate satisfaction, especially in the moral sense.
