Falling off a cliff means that you will encounter difficulties and need the help of people you trust.
Personally, I think the funeral is a good sign. Dreaming of a coffin can be a metaphor for rebirth, or a change of mind or soul into another stage, as well as getting rid of unhealthy bad habits and leaving the old environment.
Generally speaking, your life is a little confused. If you are at a loss and need help from a noble person, there will be a good situation!
Dreams are just catching shadows in life. The most important thing is to strive for an optimistic life in real life!
Good luck!
