Your plant is reacting to drastic temperature change. I leave my jade plants outdoors all season long, it has endured even 21F with some cold damage on its leaves or lose some leaves, but it quickly bounces back once it gets warmed up. It can take the cold provided kept dry or allowed to dry if it happens to rain. It is more cold hardy than most succulents, but must be kept dry if possible.
Since your plant is already indoors, just allow to acclimate once more, and as Ken mentioned, keep it dry for now.
