Dinah didn't know how much time passed while she was in a state of near-constant terror. There were old fears relived-for a time, she was back in that warehouse with the drug kingpin who'd tortured her and sliced her open. That was one of the milder memories. There were the losses of those she'd loved: from Oliver's death to Lian's, and to Sin's faked death.
There were other fears that had yet to come to pass. She lived through Dean's death and Fred's, Zoe's, Hank's, Sam's. The destruction of the City, simply losing everyone she loved and being stuck here on her own.
All of this passed through her as the toxin did its work on her.
When she awoke in a strange bedroom, Dinah was disoriented and exhausted, to say the least. She registered on some level that she wasn't restrained and was in a bed, but beyond that she simply started to fumble as she looked for her phone or comm-link. She didn't know where she was or how long she'd been out, but she knew that she needed to get ahold of someone.
