The lever on the steering column under the hood is adjustable. It may have slipped, but most probably something got bent.
After you adjust it the shift indicator may be off. If it's like my '95 there is a little lever on the steering column under the dash that has a little cable looped over it. Bend the lever until the indicator indicates which gear you are in. Use pliers because the little lever is not too sturdy and you may bend it too much with your fingers.
