VR and Thync

I dont know much about this new tech I'm seeing...things like the Thync device etc...digital mood stimulators...and I'm wondering if anyone is looking at using them somehow in VR situations...(I have also heard of something like it called Digital Drugs but havent looked into that yet)...kinda creepy but would be interesting to see if certain situations inside a VR enviroment could stimulate an emotion or feeling using that tech...maybe like meditative VR that produces a feeling of calm...or situations in a FPS or horror survival that stimulate energy...it might even already be being done I dont know...I only just heard about Thync the other day.
