Dream about colleague and now got a crush

[Peapop777]

So I've been working with colleague for a year, lovely guy, always got on really well and can have a good laugh with him.
Good looking but not my type as such so never felt any attraction plus he's happily married and talks about his wife and kids a lot.
A few days ago I had a dream about him and let's just say I could barely look him in the eyes the next morning as I just kept getting flash backs of the dream.
I'm trying to avoid him as much as possible because out of no where I can't stop thinking about him.
Unfortunately a couple of times a week we have to work in the same very small office, yesterday he was showing me something on the new system we are using and he told me to come sit closer so I could see better on the laptop and he joked after a while that he must smell as I was trying not to be so close to him as I couldn't concentrate.
He came to me a couple of hrs later asking if everything is ok as I seemed a bit off, one of my closest friends passed away a year ago so he's always since then been really understanding and made sure I'm ok.
I feel awful but I used her as an excuse as to why I'm not myself.
I don't really know what my AIBU is about I just want these feelings to go away and to go back to him being a colleague who I get on with and have a laugh with rather than avoiding him at all costs.

It was just a weird dream. Try to forget about it. He's married with kids!

Few things might help

First focus on the negative. Like does he have long nails? Scruffy shoes? Is he tight fisted? Think of the negative. There's got to be reasons why you've not fancied him up to now. I reckon you just fancy the dream version of him.

Be realistic what does getting together with him really mean? Assuming you're single and not shafting your own nearest and dearest if you fulfilled your fantasy then you are hurting his wife, a woman like you, and 2 innocent girls. What would your friends and colleagues think of you? Plus the sex would probably be awkward (fantasy hot sex is vanishingly rare) and then work would be a minefield.

Best option. Avoid him like the plague and don't think about him.

I know, all I want to do is forget it.
I'm single but even before this my stance was and has always been if he's not single then it's a not an option.

@ZenNudist
Crossed post, I would never want to be with him in those circumstances.
Yes it's definitely without doubt the dream version that has me thinking about him.
I unfortunately have no say in when we work together but all other times I am avoiding him.

It's so weird that these sexy dreams can make you see someone differently, isn't it? I remember having an erotic dream about a man I worked with. He was much older, like 65 and I wasn't remotely attracted to him but after that dream I felt all funny about him. I recently dreamt about my current colleague that way. He's much younger and gay and not attractive to me - but after the dream I could barely look at him. Very odd!
