وعن أبى هريرة رضى الله عنه قال‏:‏ سمعت رسول الله صلى الله عليه وسلم يقول‏:‏ ‏"‏لم يبق من النبوة إلا المبشرات‏"‏ قالوا‏:‏ وما المبشرات‏؟‏ قال‏:‏ ‏"‏الرؤيا الصالحة‏"‏ (( رَوَاهُ البُخَارِيُّ))‏.‏

Jabir (May Allah be pleased with him) reported

Messenger of Allah (ﷺ) said, "When one of you sees a bad dream let him blow three times on his left, seek refuge in Allah from the Satan three times (i.e., by saying: A'udhu billahi minash-Shaitanir-Rajim) and change the side on which he was lying."[Muslim].
