I'm just an internet researcher, I don't know the answer to your questions, which is why I tagged u/TrustTheTruth who has first hand knowledge, but I will try to answer them anyway.

With a gap in the dome that some souls can escape...sounds similar to gnostics?

I thought I answered that with my post. The mound builders do believe that there is a hole in the sky that souls go through. You can see that if you read their legend about Onaiazo the Skywalker.

Is what freemasons think happens after death?

I don't know what freemasons think happens after death, but it's obvious that they have taken an interest in mound builder belief systems, probably because, like you said, it's has many similarities to gnosticism and the ancient egyptian religion.

Dahmers obsession with Return of the Jedi and a Great Lakes prosecutor named Luke Skywalker are two examples that show that the masons/illuminati have taken an interest in mound builder belief systems.

And they are chipping people and vaxxing etc to prevent them joining the river of souls?

That's what I think at least. Their obsession with things like the religions of the Mound Builders and the ancient Egyptians make it look like they are after more than just depopulation and technocratic tyranny.

but if they block the exit they are trapped here too aren't they?

I don't know.

I am not bothered about dalmer

You should be bothered about Dahmer. He is not just some random criminal, Dahmer personally called the White House from a pay phone when he was on a highschool field trip and was let into Vice President Walter Mondales office at midnight. https://archive.ph/klKHM#selection-1729.1-1729.107

Dahmer is proof that there is a serial killing cult embedded in the US government.

Walter Mondale was Jimmy Carters V.P.; Jimmy Carter is directly connected to three separate serial killers.

1. Jeffrey Dahmer who visited the office of Vice President Walter Mondale
2. John Wayne Gacy, who was photographed shaking hands with Rosalynn Carter and
3. Jim Jones of the Jonestown massacre, who Rosalynn Carter had dinner with, wrote letters to, spoke at his church and visited with V.P. Mondale: https://archive.ph/fpEyW#selection-121.0-121.402

Here are pictures of Carter with both Jim Jones and John Wayne Gacy. https://i.redd.it/oyhdz3aetjo81.jpg

Here are more pictures of Jim Jones speaking at Carters rallies. https://calisphere.org/item/ac7334c3b2e0db0da8504047f4c9ce85/

Tony Podesta also had a statue of Dahmers headless victim hanging in his apartment:

Podesta also campaigned for Carters secretary of state Edmund Muskie in Racine Wisconsin when Muskie ran for president.

Here is a picture of Muskie alongside V.P. Walter Mondale, whose office was toured by an underage Jeffrey Dahmer in the middle of the night:

Less than a month before Dahmer was arrested for murdering people and chopping them up, the maintenance man who worked in Dahmers apartment complex was also arrested for murdering someone and chopping him up in Racine Wisconsin

That murdering maintenance man named Joachim Dressler who worked in Dahmers apartment complex co-authored an academic paper with a man named Charles H Faulker who is an expert on Mound Builders: https://archive.ph/Cxu0G
