I sent my info earlier but just in case you didn't get it.
What I experienced in the 10 minutes was a whirling white tornado bearing down on the tumor.
It swirled around it , inside it until it became increasingly smaller than 'poof' it disappeared.
That part was my intention so I was aware that I was creating this. The next part was not.
 
The entire brain turned the colour of fushia or bright pink and then a bright yellow.
 
That was it. Hope this helps!
Blessings,
Margaret
