I think it's to do with dreaming... Oskar does it sometimes too and says or asks for the strangest things! Their minds keep going and I think they find it hard to settle, much the same as we do at times.

Re: milk and honey.. if you do this, make sure she brushes her teeth before going to sleep! We used to give Oskar milk before bed but after brushing and he's got some decay (which has luckily arrested and stopped) which we think is from doing that... it's cos there's natural sugars in milk. So if you add honey to the mix, you're doubling that risk. Just FYI

Scary spray is just water In a spray bottle (which you can decorate or mark) to "scare away anything bad"
