Delusional or real?

I remember it very clearly for some - when I was around 6 years old I was always scared of mirrors. Because I always have the feeling that someone is behind me or coming towards me. 
(I've had a fear for mirrors for as long as I can remember)

I remember being pulled out of my bed at my grandparents house - not roughly though. I also remember being pulled towards the mirror on the closet, then I stood up and stared into it for a few seconds before being carried. 
I have absolutely no idea how but it felt VERY real, I felt the air and my pj's on my body, but I didn't feel what was carrying me. Neither could I see it, it felt like I was sitting on someones back. I asked it to bring me downstairs and it strangely did.
I had to open the door myself though before I we went towards the stairs. 
When almost downstairs I asked it to set me down and it listened again, I walked of the stairs till I reached the hallway where my grandparents were sleeping.
I asked it to pick me up again because I started to realize what was happening, but this time it didn't respond. Or so I think, because my grandpa said that he heard something in the kitchen move or being thrown off the counter the next morning very early. 

Anyways, then I walked towards the mirror facing my grandparents door and looked into it for a few second hoping for the same to happen but nothing did. I walked in my grandparents room and told them what happened and they just told me I was sleepwalking.

Look I get that dreams can be very realistic but this felt too real to be fake, and the fact I remember it.
