Hi, OP, it sounds like a terrible nightmare and i am sorry you had to go through it- i also have had relevant and coincidentally with similar symbols of something falling again and again as i try to fix it- like in your case- the crutches of the old man. I looked that up on Psychological Science and seems to signal to a internal and intra relationship we have with our goals- i am also kinda glad you woke up because the direction of dream seems to be going towards a tragic end- i am sure you must have been shaken- very sad to hear this
