Knowledge from a Past Life 2.0

Through Trials and Tribulations your memories from former lives lived begin to bleed through. You temporarily remember glimpses of the past, perhaps faded memories from ages ago or a previous life. When you make an ability check that uses a skill, you can roll a d6 immediately after seeing the number on the d20 and add the number on the d6 to the check. You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

Roll a Wisdom Save every time you sleep.

13 passes and you get a long rest.

2 to 12 you have a Nightmare and get a short rest.

Nat 1 you have a Night Terror and get no rest.
