Vein 
To see your own vein in a dream is an indication that you have built protective defenses for protection against those who would belittle and slander you.
To dream that you are bleeding from your veins foreshadows a great sadness in your future. You can escape from the sorrow that is coming your way.
To dream that you have swollen or bulging veins indicates that you often trust those around you before they have proven their worth.
Bleeding
A dream of bleeding indicates loss of strength, stamina, or drive. Bleeding may also symbolize a need for more nourishment whether literally or figuratively. Generally speaking, experiencing bleeding in a dream is your subconscious manifesting that you are on the brink of losing something very vital.
Hemorrhoids
To have hemorrhoids in a dream may indicate that you are feeling vulnerable. To try to hide hemorrhoids in a dream may mean that you are afraid your personal weakness will be exposed. Alternatively, a dream where someone is causing you to have hemorrhoids could indicate that person has irritated you by attacking your sense of pride.
