This puzzle, or at least the break-in for it, literally came to me in a dream last night, during the part of my sleep cycle where I usually have nightmares instead. Therefore I have named this puzzle in celebration of its origin.
Note: you will need to complete this puzzle on SudokuPad to get the solution code, which will pop up in the message at the end.
RULES:
NORMAL SUDOKU RULES: fill the grid with digits 1-9 so that none repeat within a row, column or box.
RENBAN: Digits along pink renban lines must be a non-repeating set of consecutive digits, in any order. Note: there are two pairs of renban lines which cross each other creating an X. These lines are to be treated as separate from each other- lines of length 2 rather than length 4.
MINIMUM CELLS: Cells with arrows around them pointing to the inside of the cell must have a digit smaller than the rest of the digits adjacent to that cell.
XV: Cells with an X between them sum to 10. Not all Xs are necessarily given.
ANTI-KNIGHT: digits cannot repeat within a (chess) knight’s move.
ANTI-KING: digits cannot repeat within a (chess) king’s move.
Sweet dreams!

Stared at it for over two hours before something in my brain got the trick, but got there! (in another two hours or so)

Very nice coloring puzzle. But the renban crosses should use different colors.

Maybe important to note that the Renban-Xs are crossing length-2 lines and not splitting length-4 lines.
Ungesundheit: Thankyou for pointing that out, will update the rules :)
