Hypno: why can't I be hypnotised!?

I try and hypnotise myself to think I'm a dog by various YouTube videos etc. I've researched into it. I know I can be hypnotised because ive had professional hypno therapy. Where I've just fallen asleep and felt really relaxed. But I want to be a dog so bad and connect to my animal spirit. Anyone have any ideas how I can do so. Thanks. And please don't call me crazy because hypno is commonly used in everyday life. Thanks
