It's really good that you are giving your daughter the message that you don't think she is wierd and acting like it's all normal...which it IS, is the best approach to take IMO.
It may be hard for her though when she is around other kids as she grows, since no doubt, they will not have been so fortunate to have a mother who still remembers the truth about things like this...and they will probably tease her if she talks about it to them. I'm sure she is a very intelligent young girl who can sense who to tell and who not to, for herself.
It might be a good idea though to remind her, in a gentle way, that others may not understand what she sees and, not to be 'careful' ,as this suggests a fearful attitude towards them, but to be discerning (if you can find a better word for it that she would understand) about who she does share her secret world with would be better, even if it's just you?
I'm sure it will enrich your relationship with her...and she can help you to nurture your own gifts again and let go of any fearful blocks you have in regards to this natural ability. Best of luck
