New Plant Already Wilting! Help??

I just got this new Venus fly trap yesterday and it was looking full and healthy even for being droopy, but now it’s wilted?? I’m currently trying to revive the smaller two (back and front right) with a grow light because I previously had them in the wrong substrate. I’m currently in Wisconsin and have had below freezing temps for the past two days, but these plants live in my warm guest room. Are they wilting because of 12 hours of grow light or because they’re currently going dormant? And if they are going dormant, should I put them in the fridge wrapped in the sphagnum moss and plastic wrap?
