A simple approach + an online dream reading
A ready-made "dream dictionary", where every object gets one fixed meaning, works badly: the same image means something different for different people. It's more useful not to look up "what water means" but to see what this dream is saying specifically to you.
A dream fades within minutes. Write it down the moment you wake up — even just in your phone's notes. Details matter, but the main thing is the feeling: what you felt in the dream and at the moment you woke up.
The plot is just packaging. The meaning is usually in the feeling: anxiety, shame, relief, longing. Ask yourself: where in waking life am I feeling that same thing right now?
Take the dream's most vivid image and ask: what in my life does this resemble? Not "what does this mean in general" but "what is this connected to for me". The answer usually comes on its own.
Most dreams are your mind processing the day, your worries, and unresolved questions — not a message about the future. That doesn't make them useless: they show what's actually on your mind.
The Nikola Blajen app has a dream reading in your own words — you describe the dream, and get a reading built from its images and feelings, not a generic dream dictionary.
