Hi sdi -- I too had a "pink cloud" experience, just feeling like a million bucks physically and mentally, very euphoric. It was somewhere in months 2 and 3. I just enjoyed it while it lasted. Since then I've had mild ups and downs, mostly up though ... things are much better sober.
I also had drinking dreams, and as you describe, the drink was somehow accidental ... like I "forgot", or thought it was a glass of water but it was wine, etc. I rarely have them anymore.
I think these experiences are fairly common in sobriety.
