Waheguru Ji Ka Khalsa Waheguru Ji Ki Fateh
Try doing it again and see if you get nightmares.
I was listening to a Katha the other day, how many people can see/hear things after doing simran/path and how they leave it because they get scared. Check this video out
Don't leave Kirtan Sohila because of bad dreams.
Kirtan Sohila is a collection of hymns
of Guru Nanak ji, Guru Amardas ji and
Guru Arjan Dev ji. These hymns
underline the pains of parting of
human beings from God and the bliss to
be achieved when one unites with God
again. To remove the fear of death.
Satguru is with us at all times and
protects us from the Angel of Death
and demons. If one unexpectedly dies
in their sleep, they will not enter
lower lifeforms. Bad thoughts or
dreams do not occur if Kirtan Sohila
has been recited. Satguru places an
iron fortress around him/her so
nothing can hurt or scare the
individual.
This is from the video description from this Kirtan Sohila video, if you don't do Sohila just listen to it.
Heres the link
Also just keep saying Waheguru till you sleep or do Mool Mantar or Say Dhan Baba Nanak
Or just say the starting of Sukhmani Sahib
AD GURAY NAMEH, JUGAD GURAY NAMEH, SAT GURAY NAMEH, SIRI GURU DEVAY NAMEH
Heres a link to the translation and video
This also refers to the first 4 Gurus. Which came before Guru Arjan Dev Ji.
Hope this helps and hope you keep doing Sohila.
Please forgive me if i said anything wrong or offensive.
