“The Gift” is a gift of healing. The 4 is a symbol and reference to a previous healing sketch.
The aliens (higher vibrational beings) are presenting a “5th dimensional” gift of healing; a two-headed snake. I had to look it up! it has to do with traditional (folk) medicine. The two-headed snake also comes up as a string (supersymmetry) in other sketches.
I wonder if traditional healers (shaman/midwife) didn’t knowingly or unknowingly make use of multidimendional shifting, when the healer(s) and patient(s) aligned their intentions, beliefs and energies with a reality of wellness.
