Which Lovecraft character is a recurring dreamer and antiquarian from Boston?

Randolph Carter is Lovecraft’s recurring dreamer and antiquarian from Boston.

Created by H. P. Lovecraft, Carter is an American writer, occult student, and dream-traveler whose adventures connect several Dream Cycle stories. He appears as an intellectual drawn toward forbidden knowledge, ancient places, and the Dreamlands.

Carter’s most famous journeys include the search for the lost city of his dreams in The Dream-Quest of Unknown Kadath and his return to childhood through the magical key in The Silver Key. He also appears in The Unnamable and Through the Gates of the Silver Key.

A common mix-up is confusing Carter with Lovecraft’s other scholars and occultists, such as Henry Armitage of Miskatonic University or Charles Dexter Ward. Carter is the recurring protagonist associated especially with dreams, antiquarian lore, and Boston.
