I've noticed this about Precognative Dreaming, the further into the future the dream connects to, the more abstract it is:

Two times when Angela in her car, she forsaw Danko's men taking her out of the car under 2 minutes before it happened, not at all abstract and just before meeting Nathan in that Sushi resturant (which has Noah's apartment above it) she forsaw what was going to be said by Nathan, except that it was Sylar instead of Nathan in the dream.


Peter forseeing himself as the explosion was one of the most abstract of the dreams, all involved in it has met or will meet him within the 2 weeks that he wakes up from his coma were around him in it as he was about to explode, not all were there at kirby plaza and some were dead at the time of the explosion.

Angela forsaw the events of Season 3 as chaos in Primatech, some being killed with four key figures being involved in the chaos in the dream, three sided with Arthur, the other was used by him:

* Knox (The Chariot) - A more business type of thug who'll follow those who he knows are stronger than him.
* Maury Parkman (The Magician) - The manipulator bringing others together being manipulated by someone much more powerful than him.
* Adam Monroe (The Devil) - The traitor and attempted mass murderer who knows how dangerous the formula could be if certain people possessed it, which gave RCR to Arthur Petrelli resulting in a rapid aging FATALITY, repairing the neural damage that the poison gave him.
* Tracy Struss (The Tower) - The temptress, the one who made a turncoat out of Nathan, who later developed a more cunning and lethal strategy.
