Supernatural elements fits because this poem is very spooky in many minute details that add up; therefore on lines 23-24 "That I scarce was sure I heard you- here I opened wide the door;- Darkness there and nothing more."(Poe, 313) This implies there was something or someone supernatural at his door that vanished into thin air.
Bleak or Remote setting fits because on lines 1 and 7 Poe uses synonyms to plain or dull to allude to the setting being very bleak.(Poe, lines 1 and 7, 312-313) Line 1 "Once upon a midnight dreary, while I pondered, weak and weary" Line 7 "Ah, distinctly I remember it was in the bleak December;".
Psychological Effects of Guilt & Sin
Characters in torment fits because the character is grieving his lost wife Lenore. Poe states his character is not happy on a few occasions. "From my books surcease of sorrow- sorrow for the lost Lenore" (Poe, line 10, 313) "Then this ebony bird beguiling my sad fancy into smiling," (Poe, line 43, 314)
Horrific theme can be applied to The Raven for a few reasons. The first of which is the character hears someone tapping at his door at midnight and answers it to find nothing. The second reason is the entire setting of The Raven; its "midnight dreary" "in the bleak December" and he is "nearly napping" reading stories of "forgotten lore". (Poe, lines 1-3 and 7, 312-313)
Psychological effects of guilt and sin fits because the male character is grieving his lost wife Lenore; and he wishes nothing more than to forget her to end his suffering. Poe states this "Respite- respite and nepenthe from thy memories of Lenore; Quaff, oh quaff this kind nepenthe and forget this lost Lenore!" (Poe, lines 82-83, 315) Nepenthe is a drug the ancient Greeks believed to relieve sorrow.
Creepy symbols fits The Raven because in the poem the raven itself represents the fact that death will always be present and we will always grieve if we truly loved them. Supporting this is a quote I used earlier for Psychological effects of guilt and sin as well as "Is there- is there balm in Gilead?- tell me- tell me, I implore!" (Poe, line 89, 315) In this quote the character is asking the raven or death if he will ever find healing or peace.
