I Found the F

You can to me carelessly I am iris and the lense
You came to me carelessly I am iris and the lense
The well now is your support
And beneath the soil the real cost
The bridge adjusting to the water, water, water, water

My arms will not be bars
In auto suggested pathways you are caught
The level inside will rise, a fallen monument lies
The bridge adjusting to the water, water, water, water
I found the fair light blossom to be sour

A prism is only walls
