How do you think the speaker feels about being alone at night?

I have always liked this poem. The conventional analysis of this poem is that the man feels isolated. He is and feels distant from family and friends. Indeed, he seems to feel distant from any human contact. The only other human being in the poem is the night watchman and he avoids him as well. Hearing a distant cry and realising that it is not for him further isolates him. I have always felt that although he seems lonely, the tone of the poem seems rather content. The night is a cloak that he wraps around him, the moon his "luminary clock".
