voltage - Got shocked by a native dell laptop charger outputting 19.5 V 6.5 A DC. It was REALLY uncomfortable, but was that dangerous?

Okay.

My laptop was running out of battery. I grabbed my charger (outputting 19.5 V 6.5 A DC) which was plugged into the wall, and as I touched the end of the charger I got some electric shock going through my body to my other hand which was resting on the PC.

And I'm basically freaking out now. It felt far from good, but honestly I don't know if it is placebo (I'm kind of scared of electrical shocks).

So... How dangerous was this?
