What makes you think she does?

I think you need to reread this situation because I didn't get the impression the wife was being unreasonable at all.

I wouldn't take it so literally. Linda is a placeholder for the wife's grievances over her husband. She is claiming that he might as well have a different hypothetical partner who is willing to put up with his antics and not get upset about it.

When people use their dreams as an excuse to express frustration, they don't mean that what happened in their dream is real. They mean that the outcome of the dream is congruent with their grievances that they are unable to express without a device.

I don't think this is a particularly healthy way of dealing with it, but just trying to give people some insight before dismissing their partners as crazy.
