What constitutes dreary has mutated, for me, I was noticing.

Used to be dreary meant weather I would rather shelter from than be out in.

Now I don't go out in any weather if I can help it, so those days of [mostly] cold rain are comforting now, as they lift the feeling of confinement and shade it into a feeling of comfortable refuge.

Ah, the comfort of horrible weather. Dreary? That is being stuck inside on a sunny, warm day.
