What do you think yandere! Wanda would do to her s/o’s dreams?
In the beginning she would start off small, standing in the dark corner of your bedroom giving you pleasant and happy dreams.
Then as she makes herself a regular presence in your daily life she will give you light and soft dreams involving her.
Maybe just simple everyday things, making sure you wouldn’t suspect that she was altering anything.
Slowly transitioning to sweet dreams about the two of you, going to a picnic, or having a day at the beach.
Introducing you to the idea of being with her through your nightly respite from life and stress.
Perhaps even making it seem like you are the one with the idea of wanting to get together, not involving her influence.
Once you are together, things will change up a bit, romantic ideas filling your mind and your heart.
However, if you for any reason start to become distant from her, or act like you want to leave her… she will alter her tactics entirely.
Giving you vicious dreams that straight up scare you into not leaving her, not now or ever.
Showing you the horrors of the world that her love protects you from on a daily basis, it’s a horrible and horrific place out there.
Possibly even giving you nightmares about your friends or family to further isolate you from them, and into her loving arms.
Of course you don’t know that she is willing to make your nightmares reality if you try to defy her in any way.
Able to easily manipulate you by the visions she plants in lieu of your own dreams, which simply don’t exist anymore.
At first she wanted to just do it occasionally to get you thinking about her, but it was quickly growing into a full on addiction.
Wanting to control the relationship the two of you share for the better, at least for the better in her mind that is.
While you would have been told about her abilities at some point, she would control the narrative so you would never put two and two together.
Wanda isn’t particularly sadistic, but she does enjoy the nights where you can’t handle the terror she provides.
Waking up crying, and needing her comfort to lull you back into a sense of safety and security.
If anyone found out what she was doing, they would be appalled but she simply can’t help herself anymore.
Nightmares won’t be given every night, she doesn’t want to seriously affect your mental health after all.
Just often enough to keep you in line with what she envisions for the relationship, and your future.
Once the two of you are married she will attempt to back off the dream manipulation if she can.
Wanting there to be a level of trust between the two of you now that you are committed to living your lives together.
That doesn’t mean she will tell you what she has done, that is something that she will take to her grave.
In the end she will do whatever she deems necessary to keep you by her side for the rest of your lives.
You are hers, and that is how you shall remain, til death do you part.
[Thank you so much for this idea! It really was an interesting concept to me! I hope that you enjoy, and that it was what you were looking for!]
