All the dream sequences that peter started having was when he first started hanging out with Charles Deveaux...he had the dream where he could actually see what was going on with his brother's car crash; ('Six Months Ago...'

And even when Charles dies in I think the 5th episode of the season...I think Charles' power is closely related to the boy that was in Suresh's dream in episode 8...he can visit people in their subconscious...it will be interesting to see where they take Charles' story...
