A method for constructing a dream reproducing model, a dream reproducing method, and devices. The dream reproducing method comprises: obtaining brainwave data of a user in a sleep state (302); performing feature extraction on the obtained brainwave data, to obtain a feature value of the brainwave data (304); inputting the obtained feature value of the brainwave data into the dream reproducing model, to obtain a corresponding output value (306); and determining, from the correlation, a perceptible object having the highest similarity with the output value, to generate a dream reproducing result (308).
