The mugwort (Artemisia vulgaris) on the right centre of the picture at the same level as the flowers will do quite a job of dream enhancement, as it happens.
That certainly looks quite like S. vulgaris - bladder campion. If you feel drawn to the plant then there is every reason to research it further. Start with looking into traditional uses.
I've often wondered whether other species of Silene, particularly S. dioica, would share the properties of S. capensis. Where I now live has little in the way of Silene spp. to be found so that thought has been on hold for a while.
Feel free to get the ball rolling for us!
“There is a way of manipulating matter and energy so as to produce what modern scientists call 'a field of force'. The field acts on the observer and puts him in a privileged position vis-à-vis the universe. From this position he has access to the realities which are ordinarily hidden from us by time and space, matter and energy. This is what we call the Great Work."
― Jacques Bergier, quoting Fulcanelli
