You don't say why you are practicing mindfulness.
Is it to have interesting experiences? And is that hey you want to repeat this one you had?
If not, remember why you are practicing mindfulness and don't let that experience distract you or become an obsession. Stick to your plan.
If you would say why you are practicing mindfulness you might get more better advice.
What you experience during any particular meditation session will be determined by many different factors that can fluctuate widely. For example, neurotransmitters, endorphins, stress hormones, blood sugar, amino acids (like tryptophan), how busy you are that day, your emotional state, how much mindfulness you have been doing recently, how much sleep you've been getting, etc etc.
Trying to reproduce any particular state is not something you can always do just by using a technique, sometimes it depends on factors that you have no way of measuring easily or knowing which ones and what levels would produce that state.
In my experience, the state you describe occurs after I eat a big meal that elevates my mood (lots of carbs and protein - like Thanksgiving turkey and bread stuffing, yams, and cranberry sauce), at some point that effect of an elevated mood starts to wear off and it is during that transition I see mental phenomena arising and fading very rapidly like you describe. But people are different so I can't say for sure if is exactly what you are experiencing or that you can reproduce it by trying to reproduce the conditions that I described.
