Sunan Ibn Majah Book 35, Hadith 21
“If
anyone of you has a bad dream, he should not tell people about how
Satan played with him in his dream.”
“A man came to the Prophet (ﷺ) when he was delivering a sermon and said: ‘O Messenger of Allah! Last night in my dream I saw my neck being struck and my head fell off, and I chased it, picked it up and put it back.’ The Messenger of Allah (ﷺ) said: ‘If Satan plays with any one of you in his dreams, he should not tell people about it.’”
“Dreams are attached to the foot of a bird* until they are interpreted, then when they are interpreted they come to pass.” He said: “And dreams are one of the forty-six parts of prophecy.” He (the narrator) said: “And I think he said: ‘(A person) should not tell them except to one whom he loves or one who is wise.’”
