Return 2- Time and Direction

While suffering from my not so uncommon insomnia the other night, I watched some late night talkshow where the host made some joke about a study that suggested that time could move backwards. To be honest I forget the punch line (something about a tv network being back on top again) but the thoughts about time being able to go backards stuck with me. Time can obviously only move in one direction ie. it can't go forwards and backwards at once. But what if it could at one point move forward and later go backwards and then move forwards- like some kind of ball with energy/force going up a hill. It gains energy and moves up this hill with great force and then loses some energy perpelling it down again BUT not reaching it's origianl point. Gaining back it's energy/force by it's down movement, it is propelled again forward- repeating this process again and again. Time must progress but what if the speed of the progression is not always constant? -thus making us go back in time every so often or making momments seem to last forever. This would account for all those crazy deja vu moments and fortune telling. Perhaps even ghosts and the collective memories/ideas. Perhaps this theory can even account for when I can't find my keys and I look eveywhere and turn to the first place that I know I already looked and they are there again. Obviously these shifts in time would not be fully remembered by us consiously- but perharps in the locked up cracks in our minds that leak when we least expect.
