I've never felt anything like it This app is amazing  everything on it works for me and I've never had any problem with it. Last night I tried the Schumann Resonance for the first time  and around 5-6 minutes in I started having vague visions and at around 8 I started hearing distorted laughter and odd voices  the visions got very strange and every time I blinked I saw static. By far the strangest experience I've ever had.
