What you are describing could well be your Pluto conj Moon aspect -- very psychic, with Pluto in first or conj Asc they always hold themselves a little aloof and there is much more going on below the surface that what is shown.
Basic astrology
Now basically your sun sign is your 'core beliefs, values, ego' and Asc is your physical body, mode of expression and mask and persona that we all wear and hide behind, but definitely not what's going on underneath. What's going on underneath is your Sun sign. Moon sign, house placements and aspects describe your emotional and intuitive responses, also describes your view of your mother, as saturn describes your father by sign and house position.
So, think of a glass milk bottle the bottle is your Asc and your sun the milk, but the milk still has to 'come out' through the glass neck of the milk bottle....
Now aspects within a natal chart represent 'facets' of our personality, because we are all multifaceted beings. What these do is 'break down and compartmentalise' these facets into smaller bite size chunks. This does take quite a lot of self analysis and objectivity to 'see yourself' and why you do certain things and behave in certain ways. Actually it can be quite good therapy...
Remember back to your school days an opposition is 180', square 90', trine 120', and sextile 60' Now challenged aspects are conj (depending on the planets, cos some like each other and some really don't) squares and oppositions. Easy aspects are conj (if the planets get along) eg: Jupiter conj Moon, sextile and trine. Quincunx is inbetween (depending on the planets) causes health strains and unresolved or hard to balance planets/energies.
Angular houses are 1/7th, 4/10th so 1st is your shop window so to speak.
