Source: The Great Interpretation of Dreams (Ibn Sirin)
Veins in a dream indicate family and relatives. Their pulsing indicates life and strength.

Veins indicate a person's origins and livelihood. Cutting them indicates cutting family ties or difficulty in livelihood.

Veins are interpreted as wealth. Whoever sees his veins are prominent, his wealth will become apparent.
