A dream of her childhood in Valinor, but there are subtle (and not-so-subtle) differences; the Trees don't shine but are replaced by the Moon and Sun, and somehow she cannot find any of her old friends and everyone looks sad even though it's the Blessed Realm and everyone should be happy, and she can't figure out what's wrong.
Everything was the same but it was not. The materials that built the homes were the same, the paths she had followed through the streets as a child were the same but everything was slightly different and off. It was unsettling.
She knew where to find others but when she went to find them, she was met with empty doors or an absence of others. When she thought to ask another as she passed them, the faces she was met with held a harrowing sadness.
It seemed endless: running through the streets and her actions becoming more frantic as she tried to find somebody, anybody but even faces she thought might have been familiar did not look the same beneath the different light.
Belenwen started and awoke with a quick gasp. It seemed only fitting that she awoke alone and even then she turned her head to glare at the cold light of the moon filtering through the window near her bed. It was the same light that was different in the dream, that distorted everything she knew.
It was everything she feared, the very reason why she had apprehensions of returning home. The fear that it would be so different, that it would be so empty and nothing more than a mockery of her memories.
No, there would be no settling down for sleep again tonight.
