Chop it off when you bring it in. Happens all the time with many plant when in contact with the ground.

What you may want to do next year is to change the soil for Aloe to a more appropriate free draining mix. To me it looks like a very dense mix and could be a reason why the plant sent out a root exploring a more suitable environment.

Thank you!! I will look for that type of mix next time I'm at the local garden center.
