My grandmother has recently begun waking in the middle of the night, roaming the house, waking us up and asking weird questions. When do the collection ladies come? Where's the lady that does my shower? There's things in my room that need selling, can you sell my slippers? etc. Would this be a type of "sundowning" they talk about? Anything we can do to try and help this situation? It's making very restless nights for us all.
