Dreaming of being bitten by a snake reflects a kind of psychological harm and trouble.
Biting the forehead means pain, because the forehead means thinking.
It's just that there is no blood in the wound. I think it's because it hasn't been reflected yet Fingers without blood suppress some impulses.
The bright red wound is very obvious. I don't know how to cure this injury.
The dream reflects the girlfriend's breakup, which hurts you.
