Sybil's Subconscious Siphon

The caster brings back memories from themselves or a willing creature who has forgotten their memories from amnesia, time, curse, or any other such reason. The caster then asks for either a specific memory or a random memory. The DM then describes a memory to the creature that the spell was cast on. If the caster asks for a specific memory the DM will relay a memory related to the question, but if the caster does not ask a specific question the DM chooses any memory that the creature does not already remember. If the spell is cast on the same creature again there is a 25 percent chance of failure that increases by 25 percent each time it is cast and resets after a long rest.
