Sudden Fears??

My 14 month old has developed sudden fears or aversions to things she used to love. Like we usually watch Finding Dory, Moana, Baby Genius etc throughout the day and she'd be perfectly fine. Now, she can be playing on the floor and I'm on the couch or in the kitchen and when certain parts of the movie come on (like the stingray migration from Dory) she'll start crying and run over to me and she won't look at the tv unless she's next to me. She's also scared of some of her favorite toys now too. Is anyone else's baby doing this? I'm gonna bring it up to her PCP at her appointment this month but I'm still curious.
