r/tulpamancy

So I started recently in all of this tulpamancy stuff, I am in process of creating my tulpa and I wanted to give them the chance to choose their own form and personality, day one I started imagine just a blue ball floating around nothing crazy, day two i started to imagine it bigger and now day three it has the Silhouette of an angel inside and it grew even bigger, maybe I just let my imagination run wild but when they appeared with that shape and size I felt a sudden happiness, is this normal?, common?, does anyone relate?
