I just wanted to help you guys who have this problems of felling strange after smoking weed. It is called Denationalization and derealisation you can get this feeling after smoking weed but i can promise you it will go away completely i may take days or weeks but everything will go back to normal. When i had this i felt like i was not in the reality and it felt like i was some kind of a ghost or something. its really hard to describe but take it easy it WILL go away. Its normal to get scared when you feel this way but it will feel better if you try not to think of it. So i hope this short text maybe helped you in any way. I made this topic just because i promised myself that when i started to feel normal again i would do it. Take it easy it will go back to normal again i promise. Sorry for bad English
