A phantom step is the step that is always never there. But you will always convince yourself that it is. The phantom step is only felt during the night hours. When you walk up the steps, and feel like you haven't quite reached the top yet, you will always hoist your leg up a bit higher just to make sure you won't tumble. But low and behold, you had already reached the top. The phantom step is always followed by a feeling of confusion and a sense of disappointment.
I feel really stupid, I've lived in this house for years and I still fall prey to the phantom step
