Neptune in the 8th gets the best sleep right after an orgasm. Quality sex just completely relaxes them! Also they're likeliest of the Neptune houses to get erotic dreams, and second likeliest to have premonitions in dreams (just behind 12th ofc).

Academia [829] in 8th may be intellectually fascinated by history, astrology, psychology, thanatology, forensic sciences, estate law, Gothic literature, etc.

Capricorn in the 8th have a talent and preference for drawing out intimate encounters. Sexually, this means lots of foreplay and teasing and build-up. In non sexual intimate situations, this means reluctance to pull back from the depths and return to the light-hearted.

Venus in the 8th only truly feel wholly accepted and complete once they make peace with their sexual identity and worth. (Aro-ace natives with this placement need to know lack of sexual attraction doesn't detract from their value.)

Ketu in the 8th is so comfy in the world of occultism, etc. Growing up they may have played with homemade ouija boards, or otherwise imagined or tried in earnest to communicate with ghosts and spirits. Also the type to experiment with magic and astrology from an early age.

When looking at asteroids, if they should fall in the 8th house, you always pay attention to death, sex, inheritance, or transformation featured in its narrative. For example, I have Angel [11911] in my 8th, conjunct Uranus. I should not focus as much on the heavenly, but instead on the idea of the angel of death or an angel in fall, which aligns with both the massive changes of Uranus and the death and transformation of the 8th house. (I also have Icarus in the 8th, funnily enough!)

Moon in the 8th is more likely to experience grief and loss, and to be emotionally invested in sex. The intuition for the occult and for the study of psychology is high, but it can also have severe effects on the native.

Sun in the 8th is more likely to benefit from, or reap rewards in the practice of the esoteric and of psychology, and they often have a talent for achieving a form of self actualization through the transformation required by such studies.

Venus in the 8th also is more likely to play with alternative fashion and aesthetics, as well as exploring darker, heavier, or more intrinsically rebellious music genres like Goth, Metal, Punk, etc.

Dejanira [157] in the 8th can be sexually victimized, or victimized for being an outlier. Someone who may be called a freak or treated as intimidating but also is lusted after and sexualized unreasonably.

This Dejanira trend alters with Saturn or Capricorn influence - this restricts actual abuse. Instead, the native has their sexuality restricted and policed, and expression of it is often punished.

Malefic Saturn aspects to 8th house objects - look out for biased authority figures. They will not hesitate to use your fears against you, or to vilify you if it suits their agenda.

However, that placement also makes authority figures magnetically attracted to you, and vice versa. A love-hate relationship with bosses and officials that is undermined by an uncomfortable sexual energy, regardless of either party's intents.

Gemini, Virgo, Capricorn, Aquarius, Mercury, or Saturn in the 8th are deflectors of trauma. They seek to verbalize or analyze the pain in a way that frames it as less personal.

Eros [433] in the 8th may be obsessed with sex to an unhealthy degree, especially the physical aspects of it. The type to be addicted to sitting in their lover's lap or pulling their lover into their own lap.

... In private, anyway. Eros in the 8th, as well as sexual planets like Mars, Venus, Juno, or Pluto in the 8th, are likely to be protective of their displays of intimacy. They may vacillate between loving PDA because it satisfies their possessive streak and hating PDA for the performative nature of it, like it feels fake.
