CHEATING HUSBAND DREAMS! UUUUGGGH! WHAT DOES THIS MEAN? HELP? lol

Hi Gang,
Ok....I have had these dreams over and over again....sometimes their the same and other times a little different like last night...My husband (in my dream) went to a new clients house at about 7pm and didn't get home till 10:30 pm and he "CLAIMED" he was doing his Laundry there! LOL CAN YOU BELIEVE IT.
Anyway, obviously he was cheating....I have had dreams of him leaving me and cheating for 8.5 years!
BUT we've been together just about 24/7 so it is virtually impossible for him to cheat...nor do I feel he would even think about it never mind do it.
What do you think about it? These dreams can seem very real and hurtful then I find myself looking at my husband funny and questioning him when I ordinarily wouldn't. What's up with this?
Thanks,
Mom! ;)
