Boy, I don't need anymore either! But, along with the trees themselves, the squirrels plant many more for me each year that pop up all over the next season. They don't plan very well either!!!!
Seriously though, I would not winter them indoors. I think try this: rake them together and let them lie to dry out a bit if they're green yet, then dig a short hole where you want a tree that can accommodate a bunch of them. Before planting, soak them for an hour or two, then dump the whole slew into the hole and cover it with soil. Consider putting a wire mesh cage over it to keep it from becoming a squirrel buffet.
Likely you will have enough popping up by late spring next year to get a mighty oak and if there are several, you could pot some (gently with acorn) up in small pots to begin to develop roots for transplanting.
