By way of supplementing Roaring Fish's answer, it may be relevant to note that in the "War Room" scene near the end of Dr. Strangelove, there is a lengthy discussion of the need for government officials to have access to a maximum-grade bomb shelter capable of withstanding an all-out nuclear attack.
As Dr. Strangelove describes it—to the increasing fascination of General Buck Turgidson—the shelter would be designed to accommodate the most important officials of the U.S. government, including (of course) everyone in the War Room. But owing to the probable annihilation of all humanity outside the shelter and to the need to remain in the shelter for a century or more while the toxicity of the nuclear fallout slowly dissipates, Strangelove says, it would be necessary to include ten women for every man in the shelter, to maximize recovery of the species:
General "Buck" Turgidson: Doctor, you mentioned the ratio of ten women to each man. Now, wouldn't that necessitate the abandonment of the so-called monogamous sexual relationship, I mean, as far as men were concerned?
Dr. Strangelove: Regrettably, yes. But it is, you know, a sacrifice required for the future of the human race. I hasten to add that since each man will be required to do prodigious... service along these lines, the women will have to be selected for their sexual characteristics which will have to be of a highly stimulating nature.
Hence the reference to Dr. Strangelove in connection with bomb shelters as fever dreams.
