Can you manipulate someone's thoughts with the death note? So let's say I write:


  Bob Shneizel Car Accident. Forgets where he lives, and then thinks about how awesome he is. Then he gets killed in a car accident at 9:30. 


Would that (manipulating someone's thoughts via what I write) work?
My take on this, is that it could be possible, but not to much use.

Based on the content shown in the series, you can only specify his cause of deaths, and the events leading up to it.

But since it would all result in death regardless, and the victim seems to be able to do nothing when they run out predefined actions.

However, it is shown that the book can order people to commit suicide. The look on people's faces seems a bit like they are aware they will end their own lives soon, so maybe it is possible, in extention.

Only thing I can say with certain, is that you would need to give it a try:

From How to Use: VI


  The specific scope of the condition for death is not known to the gods
  of death, either. So, you must examine and find out.
