Deja Vu refers to a strong sense that something has been felt, seen or thought before but cannot be inferred to be real. This is common in dreams and effects how the dreamer interprets what they see in the dream world.
In most cases, the feeling of Deja Vu comes from a literal repetition of an event from our lives (think about seeing something for the second time like riding an elevator for instance). Deja vu can also be caused by a powerful argument passed between partners with unresolved issues. Legitimate messages that you need to heed carefully or pay attention to if you want your life circumstances changed are often delivered in dreams through Deja Vu like moments.
The interpretation can depend on what steps the person had already taken to try and solve their issue, the person’s perception of their own memory, and whether or not other symbols were present during the Deja Vu dream.
