This is a wonderful question to think about, dear @sphericalart! :)
Absolutely right, the Beatles are a great example on how psychedelic experiences can push creativity, inspire you and get people new ideas.

Aaaaaw, how beautiful your mother read you some stories for bedtime in a very vivid way and so inspired you, made you more creative and let your fantasy grow! :)
This is such a big treasure. My mum did the same and I am so, so thankful for that! This really is one of the main reasons why I have such a daydreamer mind today :)
You chose your words so beautiful, they perfectly describe this gift and it is exactly what I also feel about it! So wonderful you had such a loving, magical moments creating mother! :) <3
