Anxiety???

Has anyone had weird visual stuff with anxiety? A couple of times, I've had "spotty" vision where little spots are like blocked out and I can't quite see what's there, but if I just shift my eyes a little, I can see it fine. Other times it's like little light flashes, but those go away pretty quickly. Ive have my have my eyes checked every year and have mentioned this, but other than floaters, I checked out fine. The light flashes occur mostly when I'm in the sun. about a half hour ago, I was sitting at my desk reading a text book with very bright white pages and noticed a "squiqly line" in my left eye and it kinda freaked me out. I've also had a lot of neck tension lately and do exercise a lot. I got tingling in my feet and hands and and my hands were shaking a little bit and my pupils were about half way dialated. went to the bathroom and did some deep breathing exercises and calmed down and the vision went back to normal. I feel fine but was wondering if anyone has experienced this. I also know what the warning signs are of stroke, but had none of them.
