ok when i meditate i cant seem to clear my mind because i feel like some one is gonna come into my room ( no door but has a heavy red blanket over it ) and i start to get a head ace and my whole body starts getting hot and then i start feeling mad is that normal
Maybe try listening to some music? I know music helps me meditate, i like all the music off the Tai Chi albums (especially "Earth"). You could do your meditation in a place where you know people won't walk in? You could also try a different meditation technique if you are having trouble with the one that you are trying.
Different things happen to different people when the meditate. When I meditate I get dissy and almost fall asleep. Also if your woried of people walking in you could meditate lieing down so it looks like your sleeping. And I meditate with a fan on to keep me cool.
