is it safe to enter my visualization and start dreaming while awake? i have this option but i'm not sure whether this can lead to astral shenanigans and i don't know any protection methods so i feel it's unsafe, but i want to explore my dreams more to learn about myself

I've been reading 'The Tibetan Yogas of Dream and Sleep' from the library in OP, you'll find it very useful. 
It places both wake and sleep on the same ontological plane of 'experience' placing you in full control of reality and immagination. 
Very calm vibe based on a standpoint that finds any dream useful for inner advancement, even and especially 'nightmares'.
The vary same techniques explained there are intrisecally a protection of whatever you achieve, in the sense that if you don't progress in a safe way you just have not progressed in a meaningful way.
