Hey there heavy coffee drinkers cut down your cup of coffee per day as it is proved that "who drink more than seven cups of instant coffee a day are more prone to ‘feeling’ the dead."
A study done by Durham University in the UK has reported that higher consumption of caffeine drinks produce these effects.
"A lot of caffeine releases extra cortisol into the body which may cause hallucinations."-says PhD student Simon Jones
So beware and don’t risk your health with high intake of caffeine.
