clouds in my head

So many things are not allowed in my head
So many things can hurt my brain
I'm happy having only clouds in my head
But only those that never rain

Sometimes I like to make things true in my head
And even I will find them strange
But it's a pleasure having clouds in my head
And I'm afraid that this won't change

I pick a cloud and watch it grow in my head
Like an exotic floating tree
And everything is sweet and slow in my head
The only way that things should be

So many places I can go in my head
But travelling can be a strain
A million clouds have made a home in my head
And only I can let them rain
