I think what you said in a previous post could be real. Her falling asleep watching some leave it to beaver type show and then someone like Nightmare uses that to get her to unknowingly alter reality. Maybe allowing him to expand his realm into ours. And Swords is trying to get in there and stop her while it slowly expands. I mean they could do the same with Mesphito too. Just using her wishes for a leave to beaver type life against her rather then a nightmare. They did something like that in the comics not long ago where Strange brought part of Mesphito relam into ours while trying to resurrect a destroyed part of Vegas. Mesphito could be manipulating Wanda to do something Similar. I'm excited to see where this show goes.
