Telepathy
From SGCommand
Telepathy is an ability that allows a being to read the mind of another being. Certain hok'taur have shown telepathy, but this often requires genetic advancement or prolonged evolution. Eggar was given telepathic abilities by Nirrti, as was Khalek by Anubis. (SG1: "Metamorphosis", "Prototype")
The Wraith also possess telepathy. They can only directly read the minds of their own, but they can influence Humans. (ATL: "Rising", "The Gift") However, Todd from an alternate reality was able to get into John Sheppard's mind and even got his name. (ATL: "Vegas")
