i think i'd chosen the word "triggered" mistakenly (sorry)... what i was
attempting to convey was rather the opposite than you being motivated
by some triggered effect.
someplace within you you have 'receptors' which recognize peacefulness,
fulfillment, completion, and/or other such things. it's my thought that you've
associated those sensations, within your memory, with that particular form
(of your first love). when your subconscious is speaking to you of such
qualities, it may appear to you in your dreams as embodied by that person.
