Nightmares and sensation of bad spirits following me

[Jo96]

Does anyone have experience with demons or bad spirits or something like that and have advice on it ? This is following a major awakening from doing yoga and meditation for 5-6 hours a day for 3 months straight.

 

I've been experiencing nightmares and visions of demons or bad spirits when I close my eyes. Its not really nice I don't know if it's ego backlash or some kind of mental breakdown. Maybe I over did it with spirituality? I haven't ever experienced anything like this before ..

Demons aren't real.
