I think the premise here is when you really unpack it is when someone is outside of you bed, if it on the ceiling at the end of the bed on the side of bed and it is happening to someone else. I take this example to the mind/brain it is a no wonder why that is not you that is experiencing is like that space not in the bed where the abuse occurred is symbolic of being in the mind burred away someone where. The space the buffer of what ever keeps it . I like to say what is in the brain membranes flesh skin to lighten up the mood what we are going to call the amnesia walls. It totally make sense what if those abusive moments where only like 5 minutes 10 minutes what would we especially if your extremely fragment got alot of crap to get passed to get to the trauma ones.

If i had a artist create a rendition of those in those rooms house whatever it consist of you can take it three or fours alters in the areas. I'm not saying can you externally create that inside your mind or outside. I think you can have an artist draw it probably a talented artist that would include several florid alters in their homes . I think you can understand because sometimes alters get like this order I know such and such is in this home because they are related.
