Sensory Stimulation Late Development ?

Over the last year My senses have been changing or something like that in the following ways.
I bought a packet of plastic ballpoint pens they were transparent. They glistened and were beautiful. It took my breath away.  I held about 10 of them in one hand and squeezed them together. I can’t find words for the beauty, long stretchy objects, multiples.  I so wanted to chew and crunch them. Excitement in lower torso and want to cry.
I became obsessed with household containers and bought too many. Just wanting to touch them was wonderful. Just stroking one produced an almost transcendent feeling and taste around the stomach. The flap locks wow!
A hair cream tube while washing it out. The round outlet was wonderful. It’s a circle, wanted to chew it. Beauty affected breath.
Bought a detangle hair brush. The texture and type of what are they? the strands, they are wonderful, wanted to cry at their thinness and multiplicity and softness, bendiness  and noise. 
I bought some large metal sew on snap buttons. I took them out of the box and loved them wanting to push them into my excited gasping heart area and when I stroke them with my thumb, my thumb can taste them. They are heart jewels.
As well, other things with strong effects have been: stroking plastic biscuit box, plastic on envelopes, waving sink hole brushes, rhythmically snapping scissors, smelling tables, stroking wire shelves, mesh, bars of fences, sound of pushing a basket on ground in shop.
OK I am 64 and all this only started last year in lock down.  I am diagnosed as Dyspraxic, not sure about Autism.  Can this have another explanation or could it be my ND in some way? can this develop later on I life? Did lock down open up an aspect of this?
