Not necessarily. A shared reality is one where people are discussing the same thing (within a reasonable margin) even if filtered by their individual perceptions, and drawing different conclusions.
I don't know the word for the opposite of shared reality (maybe private individualized realities), but it results in a scenario where you have nothing in common with other people other than "I saw some thing" and therefore it becomes very difficult to discuss anything with them.
