The Sandman Presents: Love Street (1999-) #3

Morpheus (Modern Age Sandman) has a cameo in the surprising conclusion to a miniseries connecting a teenaged John Constantine with the Dream King's imprisonment in the Waking World. In 1968, a ghostly apparition of the imprisoned Lord Morpheus points to further clues about the demon-like force that possessed young John Constantine's (Hellblazer) dear friend Pamela. Decades later, after Pamela's death unleashes that same spectral force, Constantine grimly prepares for an occult battle whose outcome depends on Constantine's old mate Ollie stopping John from making a grave mistake.
