Stand Name: Enter Sandman (Metallica reference)
Ability: Insomnia Inducement
Desc: This stand can cause target to lose their ability to sleep, which has detrimental effects on organisms that rely on sleep for personal health or psychological ease. Over time effects include various levels of mental deprecation, insanity and potentially death.
The user may activate it's ability on people who's asleep. When Enter Sandman is summoned, it will phase through into the target's dream, and will give the target the worst nightmare they possibly would have until they woke up. After the target were up he'll never be able to sleep again even if they used any method to go back to sleep as by the post-effect of Enter Sandman, until the target died or the stand user is forced to retract their stand.
The stand is also given alot of buff as an act of self-defense measures if the target is concious about their dream and tried to fight back. If the stand is defeated in the target's dream, the stand will return itself to its user.
Form: This stand technically doesn't have any form as people's perception on their worst nightmare may vary, but physically, it mostly take form of "The Sandman" (search it on google for more exposure) with an extra addition of letters that consist of Insomnia, Dream, Nightmare, Sleep, and Wake tattoed to his body.
Condition: Can only be applied to one target, until the target died or if the stand is forced to retract. If the target is somehow unconcious, they may be able to enter the dream world again, but they will still encounter with Enter Sandman as the stand actually didnt go anywhere and will only go if the condition is fulfilled.
Limit: The stand user has a permanent insomnia, with an exchange of having an enhanced endurance and stamina, and any sort of potential development is nullified.
