Tarantula sitting near the water dish?

[WiseWarrior]

For many years I had my G. rosea's water dish above her burrow, but moved it two days ago so she could have better access to it. She walked around her cage some, made some webbing, and plopped down by her water dish. I went to sleep, woke up, and she was in her burrow, where she stayed all day. Today I woke up and she was sitting by her water again. Is she doing this because the humidity is too low? She's never shown any signs of it previously; she isn't sluggish at all. Thanks!

she may just have decided to go there when i had my G rosea he was very active and randomly sit places in the cage.
