Deep Sleep

You start a ritual that put a creature of your choice into deep sleep. An unwiling creature can make a Wisdom saving throw to resist the effect. An effected creature enters a coma for seven days. While in this state the creature receives no dreams or nightmares. The creature wakes up after the 7 days with no exhaustion and the benefits of a normal long rest. The creature can only be woken up by a dispel magic spell the same level which this was casted on.
