Dream of 24/03/06 Higher Realm

Had this dream last night,Was in this huge place kind of set out like a shopping mall, it was all pure brilliant white but the light didn't blind me. There were lots of people around. I saw a shadow of my DH's nan (passed) and I started to try and run after her. I also saw my niece Zoe she was running up a little ahead of me.(lost sight of her about 1/2 way up ) I had to keep going up stairs to a new level but she'd be way ahead already up the next level. I got to the 'top' the area was alot smaller than the first level and there were less people around.I saw some double doors but I wasn't able to go through them, there was like a 'guard' although she/he (couldn't say male/ female) had such a loving energy and I just knew I couldn't go in...I thought oh nan must of gone in there I won't get to see her, then I felt an energy behind me and nan was stood there smiling. We hugged for what seemed like an eternity she said "it will be ok".And the dream ended.
