So my wife frequently (frequently enough, twice in the past week and I feel like i hear it bi monthly at least) has dreams where I leave her or cheat on her.
Is this common? It’s been happening for several years now and it always makes me feel uncomfortable in a few ways. When I mentioned it’s something she should look into, she just got defensive about it and that she should just not tell me when she has them. Not really sure what to think or do and there likely isn’t anything I suppose to do. Just curious if this could be a subconscious meaning or fear and if anyone had any thoughts or similar experiences.
