I get days where I'm hardly anxious and other days I have anxiety. What triggers mine is that I dream a lot more than I used too. I also get hypnagogic hallucinations and nightmares. I started googling and trying to self diagnose. That caused even more anxiety and panic. I thought it was something more serious like psychosis or something. After trying to get help for this I'm told it's anxiety. I don't google as much and usually keep myself busy.
