Welcome to my dreams!

1. [Non-Lucid]
I'm in a shop looking at these thick coloured pens, I want to buy 1 so I pick a colour (I completely forgot the colour) then my dad grabs it off the shelf (I think it was in a glass tube or something) and pulls off the lid and sticks it on the opposite end then hands over the pen which is now a black coloured pen and pull the lid off then put it back on the top (I either heard it click or felt the force it took to pull off).
