From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Sleep" (page 395).
Sleeping in a dream means heedlessness or joblessness. In general, sleeping or feeling sleepy in a dream has negative connotations except for someone who is scared, or who expects an adversities or sufferings he may experience otherwise. This is because sleep abates all fears, annihilates them and clams one's distress. Sleeping in a graveyard in a dream means a sickness. Sleeping over a grave in a dream means death for a sick person and joblessness for a healthy person. Sleeping in a dream also means stagnation, heedlessness, or infringing upon God's commands, or discrediting or denying the consequences of negating them. Sleeping in a dream also could represent a blessed journey, such as seeking knowledge or doing good deeds. It also means disregard for worldly attractions, or despite for its glitters. Sleeping people in a dream also represent mass annihilation, death, murders, rising prices, or it could denote things which people are unaware of. If in fact the people are unaware or uncertain about something, and if one sees them in such a state of slumber in a dream, it means that God Almighty will remove that blind, and they will see things clearly. If one sees himself sleeping or laying on his back in a dream, it means that he will gain power and financial success in the world. Sleeping with the face down in a dream means losing one's job, or it could mean poverty. Sleeping on the floor in a dream means owning a land, being a rich person, or
having children. Sleeping for an unmarried woman in a dream means that she will get married shortly. The sleeping of an unjust ruler in a dream means a temporary relief for the people. Sleeping in a dream also means intoxication of the mind, ecstasy, a sickness, neglecting one's duties, disunity, humiliation, or death. Sleeping under a tree in a dream means having a large progeny.
