Which part art you saying is normal? With a dissociative disorder, I'm sure it can be expected to go through times like this. The difference is when I feel like that, for me it's not normal, and it's constant. Not knowing if you made the phone call, mailed the letter, talked to someone, etc can be normal, if it's not in excess, and not impacting your life. When it gets worse than normal, and starts impacting your life I wouldn't call it normal. I guess it's just the level of how much/often/extreme these things are taking place
