Moon square Lilith (orb 1.5°) creates concrete friction between the two planets. The orb is very tight; this describes a stable character pattern more than a passing reaction.
Here, Moon in Sagittarius in House 9 brings personal dream, play, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm into House 9 (vision, belief, study, and wider horizons), with Sagittarius style (expansion, travel, belief, and the search for meaning); Lilith in Pisces in House 12 brings pure ideal, absolute demand, fascination, and refusal of compromise into House 12 (retreat, contemplation, long time, and possible confinement), with Pisces style (imagination, faith, compassion, dream, and permeability).
Concrete friction: this aspect creates tension between attachment, childhood imprint, mother image, personal dream, and a non-negotiable ideal. Visible angle: Lilith near the Rising sign (orb 5.5°) touches an angle; this aspect is easier to notice through first impression, body language, reflexes, and entry style. House 9 (vision, belief, study, and wider horizons) is in friction with House 12 (retreat, contemplation, long time, and possible confinement); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
