Stephen Kings Multiverse (connections between the books)

Everyone who has read at least a few of Kings books has probably began to notice that most if not all are connected in some way. What are your favorite connections and or Easter eggs?

I think this video has the perfect ending

When Jud Crandall tells Louis about the rabid dog downstate that killed some folks and if it had it’s shots it never would have happened...one of my favorites

also when Gage Creed’s shoe is found in the lair of Atropos in Insomnia

For me the greatest moment...I had been reading the dark tower series and the kingdom hospital mini series was on TV, yes Im going back a few years, the ambulance driver tells his partner hes gonna grab a nozzie and asks him if he wants anything, he goes into the vending area of the hospital and there is a noz-o-la machine. after blane the mono they find a takaro spirit and a can of noz-o-la.

yeah i remember that now that you remind me...i binge watched that series on dvd

I know the kids from It show up in a couyple of other books, notably by me in 11/22/63 . 

Insomnia is a book I couldnt get into, I did lasty try it quite a few years ago so should I give it another go?

I also couldn't get on with the gunslinger, made it most of the way through the first book but just couldn't get any further.

I intend to read insomnia again soon it has been so long I barely remember it
