1 hadith
Hadith 6060
Sayyiduna Jabir (may Allah be pleased with him) narrates this statement of the Noble Prophet (peace and blessings be upon him): "When a person sees a dream which he does not like, he should spit three times to his left and seek Allah's protection from Satan three times, and then he should change the side on which he was lying (i.e., he should turn to the other side)."
