I was in my house somewhere and there was going to be a wedding. 

PASTOR SHEILA: There is going to be a wedding in the household of God. Christ Jesus in the individual is marrying the personality, and the "married couple" is ascending into the higher energy centers where they will be joined to the glorified Jesus Christ.

The couple came to my house for what I suppose was the rehearsal. 

PASTOR SHEILA: The ascending individual, that is, the personality that Christ Jesus is being formed in, will have at least one rehearsal before he ascends and remains permanently above the firmament, in the higher energy centers in the upper room of creation.

The groom was the main figure in the wedding.

PASTOR SHEILA: The Groom is Christ Jesus. There can be no ascension without Christ Jesus being formed in the personality.

Don't even recall seeing the bride.

PASTOR SHEILA: The bride is the personality. She disappears behind Christ Jesus. The man is the only one that can be seen. Sometimes the woman is described as a "shadow."

I carried the groom on my back up a flight of stairs.

PASTOR SHEILA: The glorified Lord Jesus carries Christ Jesus in the individual into the higher centers.

I noticed that his black tuxedo-style jacket had spots on it.

PASTOR SHEILA: The personality is Christ Jesus' garment. The personality was still marred by sin.

Eph 5:27 That he might present it to himself a glorious church, not having spot, or wrinkle, or any such thing; but that it should be holy and without blemish. (KJV)

2 Pet 3:14 Wherefore, beloved, seeing that ye look for such things, be diligent that ye may be found of him in peace, without spot, and blameless. (KJV)

Then they came back for the wedding and the spots were gone from the jacket, 

PASTOR SHEILA: Christ Jesus and the personality, the wedding couple, had to return to the world underneath the firmament, this visible physical world, until he personality was perfected through judgment

but the procedure was the same. I took the groom up the flight of stairs on my back. 

PASTOR SHEILA: The message of this dream is that there is no way that the personality can ascend into the world above without being married to Christ Jesus, and there is no way that Christ Jesus can ascend into the higher energy centers without the glorified Jesus Christ carrying Him up there.

Ascension without these two experiences is a false ascension into Satan's counterfeit time line.
