What Did You See?

Stop, don't say a word
And if you do, just keep it a whisper
I will not be growing old here
I will not grow old

Have I seen you around here, or are you just one of my visions?
I cannot fall asleep with you standing over me
What did you see under my window?
What do you hear when the wind blows?
What did you feel under my floorboards grabbing your feet?
