I also have all succulents indoors now for the winter - we already had few nights with temps dropping to -2*C for most of the night. Days are still quite nice, but too cold otherwise.

Few are in sunnyiest windows I have - unobstructed west exposure. But as days get grayer, most will also go under lights. Sansevierias are kept in same spot whole winter long (no lights), they do not need maximum light.

I keep them under lights that are 12hrs on/12hrs off. Since they are inside with typical indoor temps, I think they are growing rather than resting/being dormant. I try not to get them etiolate too much...

I brought mine in also during rain and they already dried up. It really depends on what kind of mix or soil you are using, but under normal conditions they should not need repotting just because they were wet.
