The effects of the warp vision on living entities was demonstrated when Rick, trapped in Sleepwalker's body after an encounter with the Chain Gang, inadvertently used the beam on his former girlfriend Alyssa Conover, who was about to kill Sleepwalker in Rick's body. Sleepwalker's vision causes living bodies to twist and contort, causing intense physical agony in the process, although this effect is only temporary. The beam also has the side effect of breaking the mental control of any outside entity possessing the victim's mind, expelling the controller in the process. As a result, Rick unintentionally freed Alyssa from the domination of the Chain Gang, a tactic Sleepwalker himself would later adopt when freeing other people from the mental enslavement of Cobweb's minions, using his ability to detect mental enslavement to identify the humans who needed his help. In these cases, when he used his warp beams on their human victims, the humans suffered little to no mental trauma, only experiencing a mild that they quickly recovered from. Alyssa Conover, on the other hand, suffered both the physical pain of her contortion and a serious mental shock from the effects of Sleepwalker's warp beams, which according to Sleepwalker forced her to repeatedly experience her worst nightmares. It seems that the mindspawn demons, who had completely suppressed the wills of their human victims and had completely taken over their bodies, took the brunt of the blast. In Alyssa's case, on the other hand, the Chain Gang did not completely take over her body, but rather attempted to force her conscious mind to do their bidding, leaving her vulnerable to the full effects of the beam.
