Wrapped lines in Vim can be challenging at times. Try to move up or down in a perceived paragraph and instead of moving one line down/up you move to one of the ends of the paragraph.
To solve this you might be using
gk, but that slows your navigation considerably.
To allow vim to navigate between wrapped lines (visual lines) more naturally, as if they where hard lines, you can add the following mappings to your vimrc:
nnoremap k gk nnoremap j gj
Now when you press
k the cursor will move where you really intended for it to move. Normal
k will still work as intended.
