A character using dreamfield can project thought waves into the minds of sleeping people. This allows a psionicist to take control of dreams, and shape them in any manner they want. Even other psionicists may have their dreams invaded by this without having first been defeated in psionic combat. The attacking psionicist may not kill someone with this, or cause direct physical harm, but if he/she chooses to create a nightmare in which in the victim is slain, then the victim must roll save vs. spell at a -2 penalty without the benefit of WIS bonuses. If the save fails, then the victim suffers fatigue, and will for 24 hours afterwards take a -2 penalty to all die rolls.
A psionicist can project this power to a center point up to 40 yards distant from him/herself, with an area of effect of a 20' radius. If a character is struck during the time they are trapped in a dreamfield, then they will immediately awaken and break the effect of the dreamfield, if the awakening occurred before the end of the dream. Also, the attacking psionicist may attempt this but once per night on a particular victim. It takes 2+d2 rounds for the attacking psionicist to complete the effect.
Special Note: If the Dreamland rules are used, a character who is in Dreamland (naturally or otherwise) is unaffected by this power and cannot even be reached. If the psionicist tries this power on a dreamer psionicist, the dreamer's conscious mind is immediately awaken and alerted to the attempt. At this time, the psionicist is most vulnerable because the dreamer knows of the attempt and can do something to the psionicist while they are still recovering from their failed attempt.
