Bedtime Story does feel the weirdest because it was written by Bjork. And Bjork has a very distinctive style that was interesting for Madonna to collaborate with.
I think Erotica may have been weird for Madonna herself
Madonna’s original version of Erotica, titled "You Thrill Me" made it apparent that She is not in her own shoes when she represents the final version of Erotica. With the first version"You Thrill me", Madonna writes about respect for our differences, loving someone and her longing for someone. A very submissive, feminine approach. The final version of Erotica created the character Dita, who is a dominatrix, who talks more about sex rather than love. We know Madonna is not necessarily the character she creates.
