Chiron in the 2nd House (across from 8th)
is more known for incidences of sexual trauma and abuse.The 2nd house is what you 'possess' materially, making your body the prime possession.
I'm just playing with this---------
So, the 8th house would hold 'the secrets' you bury and keep walled-off from normal conscious awareness, but is there nonetheless?
The 12th house belongs to things in 'the unconscious' realms.
The 4th house is your deeper psychological repressed materials from your childhood experiences?
