Izzy hasn't had dreams like this in years. She used to have them all the time. They weren't always the same but many elements were similar. But one thing stayed consistent: she'd crumble away into dust by the end of it.  These also had a habit of interrupting other dreams. Not just good dreams but even other nightmares. 

They decreased in frequency and eventually, she stopped having them altogether. Or at least she stopped having memories of having had them. Not that she would've told anyone if she did. This is the first time since middle school. Maybe this is the start of a new recurrence. Or perhaps it's something different.
