In the Book of Baruch, a prophet at the same time as Jeremiah we read:
Baruch ch. :
8. I will call the Sirens from the sea, and the Lilin from the deserts, and the Shedim and dragons from the forests saying to them: 'Awake and bind your loins unto mourning, and take up with me lamentation, and mourn with me.1.
Here, we find mentioned several groups -- "sirens... lilin... shedim... and dragons..." What or who are these? According to Berossus, the "deity", Belus (we know him as Belial, Marduk, Nimrod, etc.) brought forth "hideous beings". As angels had co-habited with women of earth to create giants, and eventually hideous creatures, the fallen angels also mixed their DNA with animals of earth, developing creatures often seen carved on walls of ancient structures, referred to in myths, and ancient tales from that area... Different animals were used to concoct some strange beings, that were half angelic, and half animal...
Berossus tells us that Belus generated "men... with two wings", some with "four and others with two faces", some with "one body, two heads, one a man, the other of a woman...", human figures with legs and horns of goats", "human figures with horses' feet", "bulls with heads of men..."
Likely, this experimentation was not successful, at least not fully... The beings were noted for their evil nature, their doleful howling, and misery...
Those generated were mostly, if not totally, female, and perhaps that accounts for their absence, extinction, at least in bodily form... As the half angelic, half human beings became the ruling "powers" after their death, so these beings, after their demise, became demonic powers that persisted to taunt, seek to harm, and work against mankind. Their spirits led mankind astray, in fact, these spirit beings are the forerunners of sorcery, magick, and witchcraft. They still persist in trying to get other human females into witchcraft, etc...
"sirens"
These are sea-nymphs, (known today as the fabled "mermaids"... They were female bodies with tails of a fish, and are referred to in Isaiah 34:14 as "wild beasts of the island". The words "wild beast" is a poor translation of the heb. "iy" (ee) [338] meaning "woeful howler". The spirits of these pathetic beings haunted sailors by howling, singing, etc. to encourage sailors to steer closer to the rocks, thereby causing many shipwrecks.
"lilin"
This word comes from "lilu" meaning "to howl". A "lil" came to refer to a spirit who was attended by a serving maid, i.e. a "lili" a maid of the night. They were depicted in history as a naked winged goddess with bird-like feet. They are the "wild beasts of the desert" (from 6728, tsee-ee) "howlers" of Isaiah 34:14, and the "screech owl" ( a lousy translation of two Heb. words, "bath" [1323] meaning "daughter" and "yacanah" [3284] meaning "the alert one" [translated "owl" here because owls are alert in the night seeking prey...)
"shedim"
This word, shedim" (7704, 7708) is plural, and refers to "demons of the plain". These generated beings were the "satyrs" of Isaiah 34:13, 13:21-22, Lev. 17:7, II Chron. 11:15. The word "satyr" comes from Heb. "sa-ir" meaning "shaggy as a he-goat". They are depicted in carvings and paintings of ancient times as half goat, half human-like. They are descendants of genetic-engineering of angelic DNA with a goat...
"Dragons"
This is from the word "tanniym" referring to a marine or land monster... This genetically engineered creature was part angelic, and part sea monster... perhaps having more than one head... This is referred to often in the Bible, esp. note Isaiah 34:13, 43:20, and Micah 1:8.
All of these beings were known for "howling", and being miserable in their state... They continue to be miserable, bodiless, as spirit beings... They are referred to here by Baruch, as they were by Isaiah, Moses and Micah.... Baruch refers to these spirits for he feels so bad about the judgment of God, that he feels he is joining these beings in their howling misery...
Today they are cloning and mixing dna of humans and animals... The mixing started soon after the flood, by Nimrod (who became Belial after his bodily death... The sin of today is similar to Baruch's day. Perhaps, we should think of them as even worse sins. For now, we are in the day of grace. The whole of the Bible has been completed. Jesus has shown the love and mercy of God, by the cross and resurrection. And to add to the greatness of the sin, the fact that over half the people who have ever lived since Adam, are alive today. So multitudes more than in Baruch's day, are in rebellion, sin, shameful deeds and thoughts... The judgment of God must be announced. God is calling a fresh group of prophets to the task. Judgment must be announced, not because the prophet, or God - hates the people... Rather because God and His prophets love the people.
Through the instigation of the devil, using Belial, the mixing of dna from humans and animals, humans and angels, angels and animals was started... Some failures as the sirens, lillin, shedim, and dragons were at the beginning...
