there were lots of jerks from your high school, some that caused you pain, your minds just letting go of any problems you had with people from your past

I have never done this, but I cut and paste a response from a Dream Interpretation website. It is the Christian interpretation of dreams about snakes. Of course, you may not be in danger, but perhaps you have had some type of fear on your mind.

Snakes, serpents - represents the Enemy; demons; a bad omen; danger. (Gen. 3:1, Num. 21:4-9). Also see snake.

it probably means that you think ur high school has a curse or something and I know what you mean about feelin the pain and so just don't feel scared at all!!!!! hope i helped!!!!!!!!!! Oh and by the way were your friends hurt cuz that might mean something else.

When I was in a bad marriage, I used to dream of snakes all the time. Once I dreamed I reached for the banister on the stairs, and it was all writhing snakes. Even though I actually like snakes, they are in our culture a symbol of danger, of unpredictability, sudden danger, and so on. Maybe you have some bad memories of high school -people who couldn't be trusted, who turned on you, and so on - and they hurt you in the dream. When you awoke with no marks, that was your sign that those wounds were superficial, that they are over and done with, that however you felt at the time, they left no lasting pain or scars. And isn't that really true for all of us, if we think about it? Most of us suffered in our teen years, and if we were able to get past it, and learn from it, the pain may linger to an extent, but there are no lasting marks.
