Hi
todayistheday,

I like
LonelyButTrying's thought. It's a good possibility.
Often when I have dreams (I've had them so much, and they can be strange to say the least!), I have come to realize for me that they are trying to tell me something. They often don't make much sense, but maybe you can ask yourself what you were feeling in the dream or even when you saw the sign and had the thought about not having a mom. I know from what you said that it doesn't make logical or factual sense at all, so if I were to ask you what your little inner child was saying, would you be able to share what feeling/feelings come to mind? Does your inner younger you (see what age you feel you are when you think this) feel that you don't have a mom?
