Any one else had mind blowing experiences with Synaesthesia

I've had two in the last few years that are kind of weird as f really, and to this day can't seem to get my head around how such things took place.

The first one is I was walking around a supermarket and saw some weird looking can of something, and so picked it up not even knowing what it was never mind what flavour it was. I got the most intense taste of cherry in my life. What I find weird is how did my Synesthesia know to generate cherry when I had no clue what it was.

The next one was when I picked up an old glass vial of salvia divinorum extract from many years before. As soon as held the vial in my hand bam it was like I had just taken some, I didn't have the full effects but enough to think holy crap.
