Ok so I finally worked out that some one close to me is a median system. They themselves acknowledge that they suffer from amnesia, deralisation and depersonalisation, they have trauma in their lives but not early enough for did so they arnt did. They insist they are a single person but I have experienced them as 4 different people. What's more the areas/chunks of amnesia are different depending on who I talk to. They have different preferences in drinks, hold the body differently and emotionally react to a situation differently. I'm pritty certain it's a core based median system with the core of the identity (routines name ...) Staying the same but periferal (individual experiences preferences) split.
Eg. They know that they have done the chores have to attend appointment just finished work have a fantastically accurate body clock. But if they are drinking tea and you ask them about a conversation they had while drinking coffee they will deny point blank that the conversation ever happened.
Friends have also noticed the amnesia so it's not me projecting (an accusation one of the side/facet identities have thrown at me when I tried to bring this up)
My question is now that I think I know what is going on how do I approach this. Willfully ignoring the differences seems cruel. Some of the sides/facets are very different from each other and I have unintendedly upset them when getting them mixed up . On the other hand I'm worried that treeting them as entirely different people could push this from median system into osdd3.
And ideas?
