Dream: You’re standing on a cliff, and then you’re falling into nothingness.
If you’re dreaming of falling into nothingness, then it might show that you’re out of control or overwhelmed.
It could also relate to feeling unsupported and insecure in a certain area of your life. If you dream of falling because the floor underneath your feet is crumbling, it can have a different meaning. As you well know, the devil is in the details.
You might have different associations with the details of your dream. For some people, it might relate to the 9/11 attack.
For someone else, it might represent “falling from grace”. Even if dreaming of falling is quite common, the details are different in each and every case.
