dream - in jesus name

i had a long and weird dream, but the focus of it was that my sister (or someone) got posessed, and had like.. crazy eyes (the devil said look into my eyes). then i woke up (in my dream) and prayed for my sister, and i kept praying in Jesus name, but i had to refine it
"in the name of Jesus i ask you to come out", then i thought for a while and changed it to "in the name of Jesus i command you to come out" and it got more and more fierce and commanding. in the end the demon was cast out, but i took so long to find the right words and the right mindset.

i think i dont believe in the power of the name of Jesus enough.
