It was actually my Mom.  I also had a weird experience at that same time a day before she died - actually thinking about this it was my Birthday.  The alarm  clock went off for no reason at 11:45 am  and woke us up and I said it was a sign and expected the phone to ring saying she died, it was the day before she died that this happened.  It wasn't until after her death and I realized the time, then several weeks later when I was at her house going thru some papers that we found some info from the hospital that told of my time of birth.  She almost died on my Birthday, but I kept praying and asking her not too.  Not that birthdays are meaningful at my age anymore .  I was the last of 7 kids and had a good relationship with her.  I was hesitant about saying it was my Mom because I had posted an orb picture about her that was taken last Christmas and didn't want to mess with any of the responses in regard to the orb.

If you add the time up  is comes to eleven. Are eleven's significant in your numerology chart? Just a thought. I recently made the connection that I was born at 3:04 which adds to seven and sevens are significant in mine. Also, Maybe it was a sign ?

11:45 could be a seen as a gift  11 higher awareness warning  intuition, a master number,  the 45 is a nine vibration  calling to mind  endings, termination ,sickness,closer  very spiritual  sending love out into the world .the connection it has to your mother has been made.   .but you should not think that it ends there . it brought you  site and warning . so be very willing to embrace that it could do the same at another time .

i had a odd thing happen today that i wanted to share  today as i was sitting to my desk  .i had a phone call from a friend of my sons  they asked if i had seen him  .they informed me that my ex wife his mother has in surgery a second time because she was blooding internally after having her overiers removed.the time was 11:45

Wow, that's freaky.  Perhaps we have stumbled onto something here?  I am not that skilled in Numerolgy except that I know that I am a 5, but I am learning.
