Fear of Sleep Paralysis

While you control Fear of Sleep Paralysis, if a permanent an opponent controls with a stun counter would untap, it doesn't untap and the stun counter isn't removed.

If an ability tries to move a stun counter from a permanent an opponent controls to another permanent while you control Fear of Sleep Paralysis, that counter won't move. No stun counters will be removed from or put onto anything.

An ability that triggers "whenever you fully unlock a Room" triggers when a door becomes unlocked and the other door of that Room is already unlocked, or when both doors of that Room become unlocked simultaneously.

While you control Fear of Sleep Paralysis, opponents can't use tapped permanents with stun counters on them to pay costs that include untapping a permanent. This includes costs that use the {Q} (untap) symbol.

If a permanent with an eerie ability enters at the same time as one or more enchantments, its ability will trigger for each of those enchantments.
