Is it normal to have a dream like this...?

So, it is now night time where I am but I slept in a little late today, so I dreamt while sleeping during the day today.
It was literally the most terrifying dream I've ever had so much that it is deterring me from actually sleeping now. Anyway, here it is- I had this dream that I was watching myself dying. In the dream I was lying in a hospital bed, surrounded by family and doctors. (I was out of my body watching myself); I recall hearing my mother say to the doctor that I over dosed on 2 bottles of liquid medication. My mother and one of my sisters were each holding my hands. My sister said to me "it's okay, you really need to go home now, if that's where you want to be and you'll be happy then you can let go", she almost sounded angry and bitter. I then began breathing irregularly - short and stifled breaths, generally breathing quite funny, and as I watched this unfolding, I could also feel it very strongly and it was absolutely petrifying because in my dream I knew that I was dying. I saw a doctor rush to my bedside where my mother repetitively spoke in panic "she's going, she's going, she's going..." alongside my sister who repetitively ushered a similar response to my funny breathing. Although they had been saying I was going... I knew that I had already gone. In my outer body experience I watched a girl who had also been dying tell her doctor what song she wanted played at her funeral. I watched the girl die, peacefully, after she had made this wish. My family then watched as I died (even though I knew I had already died before they thought I did); I remember going on Facebook on my phone to see loads of posts saying "RIP" but it wasn't my name, it was someone else's name, I cannot remember the name I had read in the dream. Anyway, my sisters were all gathered together, I then went around one by one touching them, patting their backs, screaming, but nobody heard me, felt me, or responded in any way except for one of my sisters. I told her that I couldn't accept the fact that I died and that I didn't want to leave and go over to the other side (heaven); then I started to walk, then run, then creep--- I was met by a bright light so I halted. I then met this beautiful, kind blonde haired fairy-like lady who reached out her hand to me and motioned for me to come repeating the words "cmon cmon cmon"... she had gained my trust so I took one step and with that step a beam of light appeared, with my next step I entered a tunnel of darkness, with my third step I hesitated because something told me that if I took that next step that I'd never be able to go back, but a stronger voice told me to take the step so I went with my gut instinct and I took the step. I entered, with this lady, a huge openness of brightness and I felt absolutely wonderful, I felt like pain and suffering were endless miles away, I felt like everything was perfect and fantastic! I was truly, truly happy! Not because I was there or anything but just because I was. Happy.
We walked in this brightness for what seemed like forever, I knew in my head that in a few seconds I would be able to meet my father (who passed on when I was a child) and I was so so so absolutely excited and looking forward to seeing him... and then I woke up..... and I was devastated... but I noticed when I woke up that I was actually breathing funny like I had been in the dream even though seconds before I had woken up, I felt really peaceful.

I know some people might think oh blah blah it's only a dream etc etc...
I truly and whole heartedly feel that this was something absolutely greater than just a dream.. did I experience heaven?

And no. This isn't a troll. So no troll replies. Thank you.
