When on mushrooms/LSD, how do you tell the difference between fear and something actually going wrong? Because of the amplification of all emotions, fear can feel very physical and there might be other physically distressing symptoms like headaches, nausea etc. Or it could actually be something happening, like a medical emergency... The fact that uncomfortable sensations could mean fear or a serious problem deters me from psychs. Do bad trips often feel like something is wrong physically besides dark thoughts and feelings?
