Meaning of Loneliness Van Morrison

Lost in a strange city
Nowhere to turn
Far cry from the streets that
I came from
It can get lonely
When you're travelling hard
But you can even be lonely
Standing in your own backyard

Nobody knows the existential dread
Of the things that go on inside
Someone else's head
Whether it be trivial
Or something that Dante said
But baby nobody knows the meaning of loneliness

No matter how well you know someone
You can only ever guess
How can you ever really know somebody else?
It takes more than a lifetime
Just to get to know yourself
Nobody knows the meaning of loneliness

I have to say a word about solitude
For the soul, it sometimes they say can be good
And I'm partial to it myself I, well I must confess
Nobody knows the meaning of loneliness
