Islamic Interpretation of Dreams (Ibn-i Sirin):

Internal bleeding in a dream means financial losses, or it may imply sufferingfrom the consequences of people’s interference in his life. However, one will end by receiving financial compensation for pain and suffering.

Ifone sees himself wounded and that his attacker is smeared with his blood in the dream, it meansthat he maycommit a sin, or acquire unlawful earnings.
