When Aisling finished her bath, she planned on checking out the castle for a while and maybe having some food before turning in for the night. However, the moment she rested on the bed while trying to detangle her wild wet hair, she just fell asleep.
She did not fall into a comfortable sleep. Perhaps, she had been holding back her mind too much. The moment she fell asleep, the visions returned.
She could not make out things clearly. The only time she ever saw anything completely clear in her mind was that time she found Gaea. But again, the old creature had been doing her machinations to bring her to her lair.
After that, she saw a lot of strange things while in the Time Portal. Yes, she could see the future. But she had to decipher a lot before she could figure everything out.
