If in a dream you dig a hole, then in reality you should be engaged in work which does not cause in you the slightest enthusiasm. If dreamed you that you failed in a hole, then in real life you should show extreme care not to appear in the trap put by your enemy. If you failed in the hole dug by you, then, perhaps, to your hopes that you will be able to outwit enemies, is not allowed to come true. The dream in which you stand on the edge of a hole and you throw in it a pebble to determine depth can dream you, however the hole is bottomless. Such dream means that you intend to get involved in a certain adventure, without having been sure that the risk is justified. Try to weigh once again everything pros and cons.
Be sure and keep any other thoughts out of your mind before drifting to sleep as a cluttered mind can decrease the chances that you will remember your dreams upon waking. Also, focusing on remembering your dreams upon waking in the morning is another very important thing. This sounds very easy, but is often hard for some to do.
