Is it possible to be wiser when you were younger than you are now?

I often feel like I wasnt me when I was younger. All the memories of my self are strange. It seems like when I was younger I knew more and was connected in a sense to perhaps a "spiritual world" better. I don't remember a lot, but I remember I was very quite. I never spoke much, only when asked. However, on the other hand, I would always greet people on the streets when we walked around Europe (was only a toddler), but the rest of the time I was quite. I developed a sense of sympathy/empathy at an early age. I dont remember this, but I watched a video of us when we were younger. My younger sister started crying and I was only a year older, but I quickly grabbed her and hugged her to make her feel better and I held her until she felt better. I was only 4. I noticed that I seemed to have a very motherly nature to me since I was a kid. One of the most imp things: I used to have small episodes (i was like 3-4) when I felt shocked that I "was on earth" and shocked that I was in a body and alive. It felt like I wasnt me, like I was something else, in a body that gave me my physical identity of "me" really hard to explain, I had these once in a while and they lasted a few seconds. I was literally in a state of shock for a few seconds. Thats why I feel like this was something spiritual? However, the older I grew the farther I got away from all this. I stopped being motherly, Its hard for me to be sympathetic. I feel like a completely different person, and it doesnt make sense because I developed in a very healthy lifestyle and family, and never went through anythin tramatic really.
