No,  there are no negative side effects of having a demon companion when they are conjured correctly. We have a very careful screening process to make sure that you are getting a genuine outer spiritual world demon who wishes to work with you and help you on this journey. Spirit guides are a natural part of our journey here. We have spirit guides and companions around us already, they are apart of our existence here and they help us on this journey.
Demon companion are very powerful spirit guides who come into your life to help you as a friend and mentor. They are not here to hurt you, possess you, or try to damage you in any way. With our screening, they will not even shift the world around you if they know it is going to damage you or those close to you. Unlike some spirits who will take the path of least resistance, Demon Companions from S&S will actually weight the options and will take the fastest route in a way that does not brings harm to you. They are powerful and sentient beings and so long as you treat them with respect you will be fine.
People who have not worked with demons before or for who this is their first time might experience a slight headache, or feel energy shifts from adjustments within them. This is completely normal and nothing to be alarmed at. Demonic frequencies are something that not everyone has been exposed to and like anything new there will be an adjustment phase. Make sure you are grounding and cleansing and just give your energy the time it need to adjust to your new friend. These symptoms usually subside within a week of meeting your companion and beginning your work with them.
They are incredible but like most things we only recommend you bring a companion home if you feel called to them and if you feel that you can handle their energies. Demon companions are not for everyone, it is important to make sure that you are connecting with one for the right reasons.
