Idea: Possession (Patreon)

So I was browsing through /D/ on 4chan when an idea hit me: Possession as a power, ideally first another character has it and then sends you into a body of your choosing and eventually you can pick up the technique entirely.

More powerful characters can outright force you out their body or will retain their wills and watch what you do with their body, stopping you if necessary. This will include both NPC's and Companions.

However weaker characters well, they're completely yours but whether they remember or are aware of the events is completely your choice, do they remember nothing or remember what they did and try to explain it to themselves?

So options are:

1) Yes, but they don't remember

2) Yes, but they remember completely.

3) At first your power is so weak that they don't remember but develops to eventually they remember.

4) No, don't put it in.

5) [Some funny option I will think of]

So should I put this in?
