Hi Bradinn Welcome to the forum.

Yes new symptoms can come and go, and symptoms can change whenever they please.

I am a sufferer and I have massive auditory flashbacks. They are rather unnerving at first. With time and work, we learn to recognize them and work through them. They can be caused from simple exhaustion, too much stress all the way to being triggered.

There is nothing to fear. They can and do start like that. I'm glad you both recognize what they are, that gives you the ability to deal with them as a team!

Welcome aboard.
