Lord knows Dreams are hard to follow.
It's a long road
When you face the world alone
No one reaches out a hand
For you to hold
You can find love
If you search within yourself
And the emptiness you felt
Will disappear

Lord knows
Dreams are hard to follow
But don't let anyone
Tear them away
Hold on
There will be tomorrow
In time
You'll find the way

----
Lord knows
Dreams are hard to follow
But don't let anyone
Tear them away

I don't understand this part.

Please explain it to me!
Thanks!!

Answer

'lord knows' literally translated means  'god knows'. This is just an idiomatic way of emphasising what you say after tha.
'lord knows' (that) dreams are hard to follow.
Dreams are just that. Dreams. Making them real, or 'following your dreams' is generally difficult.
But - don't let anyone tear them away. 
Just because dreams are difficult to follow, doesn't mean that you should give up on them. Don't let someone destroy your dreams (by ripping them away from you)
I hope this helps.

Answer

Lord knows = the almighty creator
Dreams are hard to follow = what you wish for, as in job, family, money, etc. This specifically pertains to what you want in life
But don't let anyone = self explanatory
Tear them away = keep you away from accomplishing your goals

So, in other words: the so-called creator is aware of the fact that what you really want in life is difficult to get, yet you should not let anyone stop you from having what you want and are capable of getting.
