As you said there is something deeper going on. Often anxiety is about the unknown, new or uncertain experiences. I don't like listening to change Paraliminal before bed as often they inspire me to need to do something, even just to write, give thought to or even act on the change. So Paraliminals like New History, New Options and Get Around To It, I prefer to use at the start of the day.
Nothing wrong. Your experience was just that, an experience that indicated that change had taken place.
If possible I recommend allowing the experience with a sense of expectation. The old baggage has been released (all at once perhaps hence the feelings). Wonder what new experiences will come of this.
