Nausea dream

I'm around 15 weeks pregnant, haven't had much nausea at all these past few weeks. Last night I had a dream that I was retching to be sick (went on for a good 5 minutes). I then suddenly awoke from this dream feeling very sick... and think I actually started retching? (happened early hours of morning so it's a bit of a blur). Strange experience! Just thought I would share lol.
