Transforming into an aliens so we can be rescued from Earth

I'm at a resort with a dozen or more people who are friends in the dream. The setting moon looks exactly like an Elmer Fudd face and I rush to take a picture, but it doesn't look as good by the time I get outside. I watch as parts of the moon fall away and rush off into space. Everyone gathers on the porch to watch. An alien approaches and sprays everyone with foam from a fire hose. I ask him what he's doing. "When you die on Earth your body decomposes, but we're not leaving it here."

Nobody is alarmed by any of this, it seems quite normal.

The alien explains they're are evacuating Earth and to do so they have to turn everyone into aliens first. A woman who is an impostor alien trying to foil the rescue effort rapidly pumps herself up with a bicycle pump through her anus, but the alien wraps her in a plastic bag before she explodes, containing the attack.

As we're turning into aliens, we slide down a thin chute past underground machinery aliens have had running for years. Our faces look like Devo in Jocko Homo - the video where they have pantyhose over their faces and goggles.

We are in an orientation room, Bill Gates is playing chess with pairs of everyone at once, he just draws spaces on a whiteboard and remembers what pieces are where. I'm not very interested but my partner in playing him is very enthusiastic. I'm unsure whether Gates has always been an alien or not.

Everyone from the group gets on unstained wooden bicycles that fly. I pick the only one that fits more than one person - it fits three people - but only one other joins me. Flying off and merging onto a highway, we encounter another group of aliens flying the wrong way. We stop to explain the custom of driving on the right side of the road. We encounter several other groups of humans transformed into aliens. Each group of transformed humans is in the style of alien invaders from different book or movie. Most look like some sort of Teletubby, all uniform in color.

Everybody is following along with events as they happen in a book and two people in our group have earlier editions of the book where different races of aliens were used. Confused, they had stopped reading and just went along with what was happening.

It's explained that a certain type of insect spray is irritating to our new bodies, but it's actually good for us and a little bit is put in everything we consume. A few sprays are put in the air so we can feel its slightly irritating effects. As an example of how it's actually beneficial, the alien sprays a great deal on a man/alien with a plaster cast on his leg. The swollen leg begins to heal before our eyes, but then his body begins to decompose and all that's left is his skeleton. A human woman who has not been transformed is being prepared for decapitation with a sword execution style so the aliens can merge her with the man who just decomposed. They will be both people in the same body. The woman either doesn't seem to mind or doesn't really believe she'll be beheaded, but she is. He head flips around and lands perfectly back in place on her body.
