1963, Book Four: Tales from Beyond

This comic book is Issue #4 of the series "1963", and features two stories. The first one involves the character "N-Man", analogous to Frankenstein's creature and The Thing but with Reed Richards' intellect, who is sent to investigate what may be an expanding dimensional rift, or type of "dimensional sinkhole" dubbed the Shimmering Zone.
The second story involves yet another type of rift in time involving "Johnny Beyond" a beatnick living in 1963, as his flat becomes a type of ground zero for a time bubble and involves his future alternate reality counterpart from 1992, as all involved try to determine what is happening.
