I do have gauzy memories of other experiences in the past that felt like this. Camping trips with my family as a little girl, where I played endless imagination games or swam for hours at a lake. And yes, I have memories that are not favorite, that involve pain and suffering, and for me those are always more vivid, and they demand center stage. Over the years I've developed a practice to turn my attention away from them and to deliberately focus on the good. I don't judge or block the negative, yet I try to give what is positive equal attention.
This applies to future, too. I'm very adept at doom thinking and worries, and I've rarely been a dreamer about future plans and aspirations -- it's as if I'm afraid if I dare dream of something I want, "something" will call it arrogance and teach me a lesson by not manifesting that. I know this is rooted in several things: my personality, which is inherently attuned more to negatives; an authoritarian father who wielded power destructively in childhood (and adulthood, to be honest); and a religious upbringing focused on sin, humans being inherently broken, guilt, and fear of punishment. So I have spent my life navigating and learning how to live in a way that allows me more "favorite" times. At 63, I'm getting better at it.
