i had this pain in my head, it was so intense,i cried and cried and started non stop smoking which further intensified the pain. all of a sudden my breath stoped. i was confronted with 3d like entities asking me to go up or stay in this world. i was in strange state and very fearful, remaind undecided so the entity left. but my body feels soooo weak i even cant stand up. tell me what to do?
