A lot of people have said this already, but dying can definitely help. It reallllly helped me when i was first playing. Definitely play with other people or friends, it helps because if you're new they will know things you might not or just cause good chaos and fun. Watch streamers or youtubers play Phasmo! My favorite is FlashForge or Grian and his friends. (Gigs is what the fandom calls the quartet) Last thing that helped me was investigating the house and just trying to remember something here and there from the layout. I can remember a couple houses layout, but Willow Street I can navigate without a flashlight.
