Dream state? Asked Penny to herself in her mind. She had initially thought to ask father Antonio about it but she never came to ask after realizing that the man didn't know about it.

Because there was a possibility of the present memories being wiped out.

None of us are in a hurry to know what happened in the past," he knew the consequences in meddling with fate, especially the current situation where Penny's mind was delicate. Before it was only during sleep which was rare that she experienced the flashback but right now even the shortest duration of time the memories would come to leak out but they were never in the whole picture.
