The grave is one of the symbols that should be interpreted counterintuitively. A grave in a dream promises strong health, long life, and well-being. Having come through such a challenge in your dream, you will wake up reborn. To see someone you know in a grave indicates that this person will live a long life.
Tools in dreams mean your abilities in real life. Wrenches, saws, power drills, nails, hammers, in fact, all represent abilities, resources, and skills you must use to get something done. This dream makes you use your mindset, makes you focus on your goals. You will get ahead by using this constructive progress.
