You mentioned at least 4 tents. I don't know if it was exactly 4, but Jungians consider the number four to be symbolic of wholeness and integration. It is found in many cultures and religions as representing wholeness (for instance, a mandala has four sides).

You've had dreams before about living above the ground, and you had a dream about climbing trees. Although Thunder Bow sees a positive association to the tents, I keep wondering if this represents an attempt in your psyche to live "off the ground" (ungrounded) as a way of coping with scary feelings.
