Is my mom having delusions? I thought delusions were in later stages?

Lately I've been making homemade pizza. I buy a dough ball at the store and roll it out and add all my own stuff. I like to cook but I've never been a baker so working with dough was new to me. So, my mom comes over for dinner a lot and loves my pizza. She starts saying how she used to make homemade pizza "all the time" when us kids were growing up. That morphed into that she made bread all the time. She even expounded on it saying she used to recite a rhyme to remember the steps and ingredients.

I have ZERO memory of her ever making either one of those things. It didn't happen. I started to wonder if she was thinking about her own childhood when she lived with her grandmother and mother and it was her grandmother who made bread.

Then last night we were at her place and she looks at me and says- "I can take care of that grey hair for you, all it needs is a rinse". First of all, my hair is not grey. I have maybe three grey hairs and the rest is brown. My husband was shocked- he said She doesn't have any grey hair. My mom actually said- Yes she does! It just needs a rinse. WTF.

When my mom was 15 she quit school and she went to cosmetology school. She did cut hair for a brief period. She never cut our hair that I remember. But then she said the most bizarre thing. She said my DAD went to beauty school too, and cut hair for awhile. NO WAY did that happen.

I didn't argue. I just changed the subject, but it kind of scared me. Are these hallucinations or what?
