I didn't exactly assume I'd wake up there . I assumed that I've shifted and this 3d or whatever I'm seeing right now is an illusion , that I am in DR in 4 d and thats what matters . Then I was just chilling after coming back from a univ class and meditating and stuff and shifted. I had no symptoms tho . It was real , as real as this reality ! I did reality checks ( I slapped myself really hard so I'd feel pain lol , defo not recommend) . And I came back with intention . I said OK I'm in my cr now ( affirmed I've shifted back) and that moment I shifted back . Shifting back was so instant lol I couldn't even comprehend .

So basically I assumed my 4d is TRUE and my 4d became my 3d . Hope this helps !
