Silsilat al-Ahadith al-Sahihah

Abu Huraira (may Allah be pleased with him) reports: A man came and said: I saw in a dream that my head was cut off and then it rolled away. The Messenger of Allah (peace and blessings be upon him) said: "Satan comes to one of you and presents frightening images, and then in the morning he begins to narrate them to the people."
