Waves of nostalgia

swept in without warning, pulled me out on its currents.
In its wake, I allowed myself to indulge in the stored memories it called up.
How interesting, how amazing the concept of memories is;
Chemical reactions, connections formed, which when strengthened will be stored within networks of a specialised type of brain cells called neurons.
Some memories, as if actually etched into the brain, are so vivid like they've only just happened yesterday;
Others, so different from your current reality, of situations and people changed, seem so faded it makes me wonder if I might have dreamt them up or were they just part of my active imagination? A make-believe mistakely stored as a memory?
I can't help feeling melancholic.
Does the heart recall emotions as the brain does?
Because the feelings attached to those memories return as I recall.
Beautiful, bittersweet memories, of good times, are meant to be savoured, I like to think, so long as I do not get trapped in the past of what could have been.
An email, like a fingersnap within my brain, I wake from the hypnosis, roused from my musings.
