We’re actually done with all of the artifacts from Doctor Strange. But there’s one last kind-of interface that’s worth talking about, and that’s when Strange assists with surgery on his own body.
After being shot with a soul-arrow by the zealot, Strange is in bad shape. He needs medical attention. He recovers his sling ring and creates a portal to the emergency room where he once worked. Stumbling with the pain, he manages to find Dr. Palmer and tell her he has a cardiac tamponade. They head to the operating theater and get Strange on the table.
When Strange passes out, his “spirit” is ejected from his body as an astral projection. Once he realizes what’s happened, he gathers his wits and turns to observe the procedure.
When Dr. Palmer approaches his body with a pericardiocentesis needle, Strange manifests so she can sense him and recommends that she aim “just a little higher.” At first she is understandably scared, but once he explains what’s happening, she gets back to business, and he acts as a virtual coach.
