I had the events of my first 5-8 years all messed up because that is how I felt at the time, all messed up. Therapy was able to straighten out that flow quite a bit, as I learned the order things actually happened in and undid some psychological merging/switching of events I'd done.

I use to get "jerked back" in time by sights, smells, memories, and other sensory things happening. It was like I was grabbed by the scruff of my neck back 20-30 years suddenly and was not a pleasant experience! I'd have to scramble in my head to figure out where I was or what had grabbed me, etc. That too got straightened out with therapy so it doesn't happen anymore. I don't miss that; I use to complain to my therapist because I felt so helpless to know when it would happen or what had happened and was always afraid I'd get "stuck" somewhere else.
