Not sure if this is a joke, or not.
I am under the impression that you think spirits gave you this dream for the sake of April Fool's.
Well, I believe God has a sense of humor. Life would be worhtless if we did not laugh and enjoy it. He gave us the ability to laugh, so He must assuredly laugh too.
Evil laughs at us, and our follies, and plights cause them delights.
As for the drream, well, what did you eat before bed?
Seriously, dreams are complex 'signals'. No idea what your dream means, but if I were to guess, you may have been having some serious suppressed issues with your wife, and found yourself either resentful or upset with her. The dream was a way of showing you what the seperation would mean to you in a deeper level.
You would much rather die than face the pain of seperation.
I might be positively wrong, and I am sorry. Just guessing.
