Blood-sucking Parasitic Little Tick

I was in a van with people I knew, traveling on an on-ramp to an interstate. I was in the middle seat in the back. All of a sudden something started bothering my left ankle. It was itching pretty badly. Then I reached down and plucked a fairly large tick off of my ankle. I looked at the size of it before killing it by pinching it between my finger nails.

Symbols

Tick: To see or be bitten by a tick in your dream, suggests that a relationship or situation is sucking all the energy out of you. Ask yourself what in your life is causing you much exhaustion.
Interstate: To see a highway in your dream, represents your sense of direction and your life's path. Consider the conditions of the highway which will reveal how much you feel in charge of your life. A smooth, straight highway signifies inner peace, while a winding, bumpy road reflects emotional distress/disharmony.

INTERPRETATION: On the road of life, I have to eliminate (or am already eliminating) the things that suck the life out of me. Or.. Perhaps driving so much to be (in the middle) with my friends is draining my energy (but the sacrifices are worth it).
