Their Mars in your 12th house

They stir up what you hide

In synastry, you place one person's planets into the other person's houses. When someone's Mars, how you act, falls in your 12th house, Depth, that part of them shows up in the part of your life about dreams, hidden patterns, solitude.

What it's like

Frustration you haven't admitted, anger that comes out sideways. This person can trigger old feelings you keep tucked away, which is uncomfortable but useful to notice.

The good

They bring hidden feelings to the surface

The tension

Unspoken irritation can build up behind the scenes

It depends who they are

The same placement plays out differently with a partner, an ex or your mum.

If they're your partner

They stir up what you hide

This person's temper touches the feelings you keep tucked away. It brings buried irritation out, which is useful if handled and awkward if not.

If they're a crush

They set off a hidden urge

This person sets off feelings you struggle to place, restless energy or a nagging want. It comes out sideways at odd moments.

If they're an ex

They fought you in the shadows

This person's anger and drive were hard to pin down: simmering, indirect or unspoken. Things unsaid in a row do not go away on their own.

If they're a friend

They stir up what's under the surface

This person can set off feelings you hadn't noticed. Their energy brings out hidden irritation or restlessness, which you may only spot afterwards.

If they're family

They bottle things up around you

This person may hold anger rather than voice it. You can feel the weather change before a word is said.

The other way round: Your Mars in their 12th house

You stir what lies beneath

Your Mars in this person's 12th acts like an undertow. They may feel restless or oddly tense around you, with irritation or desire that has no obvious cause.

About Mars

Mars is your drive: how you go after things, how you get angry and how you get moving on a Monday. It's courage, sex drive and the urge to win, all in one slightly sweaty package.
