Dried fruit - raisins etc

I would think that this is a coincidence rather than linked to dried fruit. I have not heard of anxiety being increased for these reasons. Try to relax and stay off the dried fruit for a day or two. Anxiety can make is find all sorts of reasons for the way we feel. 

I eat a lot of dried fruit and have never had this effect.  But it might be worth looking it up on one of the health sites online to see if anyone knows about this.

I used to know someone who had a genuine phobia of raisins! Can't think of any other reason they would heighten anxiety...

I just googled this dried fruit - anxiety connection because I got a bit anxious after eating dried fruit almost instantly. I'm not sure if it was the eating that caused this yet.

But at least in your case I think the dried fruit might make you dehydrated during the night - at least if you eat them late - because the absorbing water and because the body trying to get rid of the excess sugar by urination. And dehydration is known to cause anxiety and therefore poor sleep which causes anxiety. 

And you could be allergic. perhaps to the fruit proteins themselves or to some mold that is growing on the fruit. 

Or it could be some mold-produced toxins.  did you eat organic? Were they treated with vegetable oil? I'm guessing the oil is a sort of mold preventing measure
