You should always lightly sand between coats with 220 grit,no matter what. Then wipe the dust off with a tack cloth. Sanding removes any impurities in the finish rather than impregnating them under the next coat. The result will be a smoother, clearer finish that won't snag your socks.

Sanding also promotes better adhesion between coats, something as X pointed out should always be done between coats. Depending on where you ran out you may need to recoat everything to get it to look nice.
