this week's whacked out LOST theory (besides my own)

I think we are being led to believe that Desmond travelled back in time when the hatch imploded. However, I think what really happened is that he went into the future near the point of his death and then from there went back in time where he ended up on floor with spilled paint sharing an apartment with Penny. I think he is not seeing the future but instead remembering the past. If he only went into the past he would only remember things up until the hatch imploded but nothing after that...unless he went into the future too. It would tie-in to being able to know when to read the last Charles Dickens book before dying. Supposedly people have their life 'flash' before their eyes and Ep 8 of season 3 is called 'Flashes Before Your Eyes'. Make any sense? I think the paint can had the letters 'FUTUR' on it - I may be mistaken. It's my 2 cents anyway.
