I wrote a beautiful reply in the wrong place and it vanished but here it is again:
Your feminine nature is dim in your life, but its in the same room so in the subconscious not too far from the surface of who you can completely be. You protect this feminine energy, archetype, aspect of your personality from the approaching scorpion. You take the bite unknowingly and feel the pain of protecting her, maybe even hiding her from the poison of the scorpion. Its painful to let your masculine self subside to allow the feminine to surface. And the size of the scorpion matters considering you use the reference of 'the size of a pillow" meaning the amount of poison is enough to put her to sleep or smoother her to death.
Keep working on bringing that aspect of yourself in balance with your masculine side. Its not easy to define in todays world what is feminine and masculine. Its so stereotyped but some examples of feminine would be a caring and compassionate nature, one that is patient, nurturing, willing to teach, do things from scratch like giving birth to an idea without knowing the finished product.
Take care, Camille
