Treated across the collections as a posture of appeal rather than a matter of doctrine, and read the same way whether or not the dreamer holds a faith.
Prayer turns up in the dreams of the devout, the lapsed and the entirely secular, and the interpretive tradition treats it as a posture rather than as a doctrine. Read across the collections it comes out as appeal: the dreamer reaching towards something larger than the situation, and in doing so acknowledging that the situation is larger than they are. A second reading, present in most cultures that keep dream records at all, is simply relief, the settling that follows having put something down.
Dream literature exists in many religious cultures and each reads this image through its own frame, so there is no single answer to give and this entry does not attempt one. What the various traditions have in common is that they read the act rather than judging the dreamer. Nothing here says anything about what your faith teaches, whether you hold one, or what a dream obliges you to do. That is a matter for you and, if you want one, for whoever you would normally ask.
Whether you were praying alone or among others is the usual first question, since collective prayer is generally read as belonging and private prayer as need. Whether you could find the words matters too, and being unable to is a frequent report that readers connect to feeling unable to ask for help while awake. Praying for a specific person is treated as concern for them and nothing beyond that, and praying in a building you do not recognise points at unfamiliar ground rather than unfamiliar belief.
People who pray daily dream of praying, in the same unremarkable way that people who drive dream of driving. If it is part of your ordinary week the dream may carry no symbolic weight whatsoever. And if it is not part of your life, the image still belongs to you rather than to any institution: what it meant inside the dream is the only reading that counts.
