Danny perspective
As we're being pulled through I feel pain it was like when I turn on the ghost portal. I sense some sort of energy surrounding us. When it hits me the energy is absorbed as I realized the change was not just to my ghost half, but to my human half as well what should be gloves appeared I noticed claws showing causing momentary pain as flames engulfed them up to the wrists as my body twisted and turned as the blackish hue covered it as it finally hit me, the two halves where merging.
I felt my ears prick up on my head as I held my body feeling what should be white shoes instead become engulfed in white flames revealing clawed feet as another tail burst from my back each tipped similarly with blue as I close my eyes tight. I can feel my whiskers stretch further my face only slightly as my hair got longer finishing my transformation. Opening my eyes I saw how I was in the process of getting smaller. As I stood on my now almost quadruped legs.
Thars a bright lite I close my eyes as we enter the other side of the portal. I open my eyes look to my friends and sister I see that they had been regressed and unconscious but otherwise fine. I try to get up only to become dizzy. Blinking my eyes and shaking my head a little. My vision becomes clear for about second before becoming blurry and blacking out.
