What you are describing are the actually normal beginning awakening experiences of someone who has for many different reasons, found themselves with less baggage hanging them up as they walk along worldly life. Its common for children to have these experiences but we often forget them or only remember them as fuzzy distant fond memories.
It can be likened to in a moment out of thought, remembering and experiencing who u really are. Waking up for a moment and appreciating and enjoying the attributes of being and then in the next moment falling asleep again back into a set of circumstances in which those same attributes arent as readily known, experienced, realized.
Classicly it has been stated that we arent humans having spiritual experience but spirits having human experience, and one I also like is, that we dont live in this body, this body lives in us. So when we start to re realize such realities the deeper implications, the powerfull attributes of such truths outweigh, overcome and transcendentalize our normally expected experiences of conventional human existence. Brief interludes of the joyfull reality of beingness.
If you look for it you will find in literature the stories of people who have had these experiences like you mention and eventually like you desire, the inoften becomes daily experience. No longer colored and acted upon in the "normal" way we all are used too, but rather like you shared; but all the time, cause they have re discovered, re realized their actual being and its radiantly beautiful enjoyable nature.
Read and study to strengthen your faith that such things are real and to be expected. The predicament is that if we try to reproduce them we bring that which is normal and constituantly us, into the worldly realm of desire and manipulation, and thus approach with misstaken ideas what is already us, for something we must aquire. If we only seek to regain past experiential joy we miss the joy we already are.
Untill we know/live the truth, we study and work to learn, we share.
Youve been shown and you now will be challanged. Without expectation learn to relax into your beingness and share the presence of your life with others and know that tho there is much difficulty, youve been shown the tip of the most marvelous beauty and that that beauty is always here, as us as you.
