The dots and dashes are Morse Code as noticed by @Randal'thor
When it is translated to text it reads as follows:
We've known each other for so long, your heart's been aching
We both know you're too shy to say it
Inside we both know what's been going on
We know the game and we're gonna play it
And if you ask me how I'm feeling
Don't tell me you're too blind to see
Never gonna give you up
Never gonna let you down
Never gonna run around and desert you
Never gonna make you cry
Never gonna say goodbye
Never gonna tell a lie and hurt you
These are
the lyrics to 'Never give you up' by Rick Astley, it's a rickroll
As a bonus
'Fall MMXVI'
is Roman numerals for
Fall 2016 (Autumn 2016)
which was the season and year when the puzzle was posted...
