Emily Dickinson's I Heard A Fly Buzz

I liked this poem better than “I heard a Fly Buzz.” I still think Emily Dickinson’s poems are kind of confusing. This poem’s is about a speaker who encounters death. The speaker is on a ride with death passing through playgrounds and a setting sun. What I thought was confusing about this poem is the speaker’s thoughts about death. The speaker describes everything so calmly. I wonder if the narrator is happy about dying or has faith that there is an afterlife. There can be so many viewpoint of what the narrator might think about death.The only hint I got from the poem that the author had faith in an afterlife was when the speaker stated, “I first surmised the Horses’ Heads were toward Eternity.” I am not sure about the speakers religion
