In order to unlock this trophy you will have to complete majority of the "Mixed Signals" side mission.

First you will have to buy a couple Typhon powers using Neuromods. Doing so will randomly spawn a Nightmare. Nightmares are one of the toughest Typhon enemies in the game. Now a Nightmare isn’t guaranteed to spawn, so It is recommended to save the game, and trying to spawn it by buying a couple typhon powers. If it doesn’t spawn, then reload the save and continue the story for a bit and try again.

Once the Nightmare has spawned, kill it. It might be a tough battle, but you’ll have to kill it if you want the trophy. Once the Nightmare dies, January will randomly call you, and will give you the "Mixed Signals" side mission. Now if January doesn’t call you, kill a couple more Nightmares and you will eventually get the call from January.

The first task in the side mission is to head to the Hardware Labs area and repair a computer terminal. Follow the objective markers to find the computer terminal. You will need the "Repair III" Human ability to fix the computer terminal. It will cost 13 Neuromods so make sure to have that many. You will also need 8 spare parts to fix the console itself. Once repaired interact with the console and raise the object. Remove the component from the object and move on with the mission.

You’ll have to head out to the Talos Exterior and install the component on a satellite. The satellite is constantly moving so it can become annoying to keep up with it. Once you install the component, head back inside.

Now open up your inventory and check your TranScribes. You should have 2 new TranScribes. One for Attracting Nightmares and one for Repelling the Nightmares. Activate the Attract Nightmares TranScribe to earn the trophy.
