I'm not sure I want to find out myself which skills to get (I'd feel like I'm cheating on my physical gf), but I think for satisfying the curiosity of how it would work, your Reddit post was pretty informative

Imagine how they would look being in that position. The shadows, the lighting. Do it as best you can. Let them move the image around as they would a mindscape form. Eventually you'll reach the point where your memories show them there and it becomes more and more believable
