Could dreams be the brain’s version of prayer?

Yes—at a broad human level, dreams can be seen as the brain’s private version of prayer.

Both can help with emotion processing, meaning-making, and mental rehearsal. Dreams often mix memory, fear, and desire into symbolic stories; prayer can do something similar in a conscious, directed way by giving feelings a form and placing them in a larger purpose. Both also turn attention inward and can reduce stress or help people work through difficult experiences.

The big difference is agency: prayer is usually intentional, language-based, and aimed at something beyond the self; dreams are involuntary and generated by sleep biology. So the comparison is best as a metaphor, not a literal equivalence.
