dreams of babies...

does anyone else dream of having a baby before they've conceived or before finding out the gender? I had a couple dreams in past weeks about being full term with a girl. but last night and during a nap today (so 2x in one day) I've dreamt about a little boy newborn and again around 1.5 yrs old. And my husband had a dream last night he was playing at home with a son. do dreams mean anything? or is it just our hearts desire so strong that our dreams are making it a reality while we sleep?! just thought id share
