Afterwards in waking life I just felt reassured that no matter what I do, I know it will be okay.

I had experience with Magic Mushrooms. After the lost of time, thoughts of wonders, emotions that were the strongest and best I have ever felt. The calming down, in the moments where weird circus music is playing in my head. Images of weird objects that I don't remember ever seeing circling along with the music. I open my eyes and in this moment I'm over my head. Sadden with such joy, tears that make feel cheerful. It was at this moment where I uncover my head from under the sheets and to put it simply I know everything is going to be okay, everything will always be okay. FYI, I like to use Magic Mushrooms to give me insights of where I am in life, to free myself in a way that feels spiritual(I only do them twice a year).

It is interesting to wonder whether there is a continuous life in "dreamland". I can see reasons for both there being and not being but I don't know.

What will you say your reasons for there being and not being? Just talk, it doesn't have to be something you understand how to explain. It might be something that needs more than one head to grasp the idea.
