Effect Summary

Target loses ¼ its max HP

every turn as long as it's asleep

Nightmare applies a status condition to the target that causes the target to take 25% of maximum HP

damage every turn while asleep

The move itself does not cause the target to fall asleep

Once woken up, Nightmare is cured.

In Gen 2 there is a bug that using a Full Heal or Full Restore does not cure the Pokémon from the effect of Nightmare.
This only occurs for target's. The player's own curing effects work as intended.
In Gen 3 there is a bug that causes Shed Skin to not cure the Pokémon of the Nightmare effect (it will again receive damage if it falls asleep).
In Gen 2-3 Nightmare bypasses accuracy and evasion checks to guarantee a hit except in the semi-invulnerable turn of moves such as Dig and Fly.
From Gen 8 onwards this move can not be selected in battle.
