SCP idea (dumb probably)

Just idea
Name: Night by night,dream by dream
(Not too good at English)
This is basically the idea of an SCP that's sometimes been in your dreams,you just didn't see him yet.He is passive until you realise he's in your dreams.Then night by night he will come in more and more dreams,become more agressive in your dreams, basically turning all your dreams into nightmares until he makes you kill yourself.
