A sudden turn on the road to something in your dream means that you have reached a turning point in your life.
I came to a place where tombstones were customized. Here, it may be related to job hunting and work problems.
There are many people of various identities who sell me their tombstones. Tombstone is a status symbol, representing position.
People of all identities refer to all kinds of choices, waiting for you and facing the choices of life.
Of course, I don't know if your reality is related to work, and I'm not sure, but there must be a choice.
