Mirror of Sleeping Vigil
This jeweled mirror grants you gain greater control over your dreaming self. While invested, you can watch over your sleeping body from the Dreamlands, letting you see your own body and a 5-foot emanation around you, though you can't hear, smell, or use other senses from your dreaming self. You do not take the -4 status penalty to visual Perception checks in that area or gain the Blinded condition from being Unconscious against creatures in that area. As long as you fell asleep voluntarily and not from a sleep effect, you can automatically wake up from sleep if there is visible activity around you.
Traits
Effects and magic items with this trait involve false sensory stimuli.
A character can invest only 10 magical items that have the invested trait. None of the magical effects of the item apply if the character hasn't invested it, nor can it be activated, though the character still gains any normal benefits from wearing the physical item (like a hat keeping rain off their head).
Something with the magical trait is imbued with magical energies not tied to a specific tradition of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
This effect can cause a creature to fall asleep or get drowsy.
