Oh... I didn't know that sending-all-energies worked with the imagination method. At least by some reason unknown to me I never tried to send back the negative energies to whomever they belonged to. Perhaps I thought it would do the discarnate harm or maybe that it wouldn't work.
And I never thought of the Seeing-It-Not-There, by some reason, perhaps I thought I needed to
see something at myself to succeed with that technique?
I'll pick out my book and read about that section again.

Anyway, I requested verbally healing from guides, and over several days, the bad feeling disappeared. At a few times I got the impression of someone discarnate trying to get my attention, I told the person to look for friends & relatives and move to them. It helped three times. This also happened over some days and I could feel their heavy energies from time to time.
The request for healing was the thing that worked best. I decided to be as open as possible. I have one TMI healing H-S Metamusic CD and listened to it. I also read some stuff at the time from a blog and asked questions like "
who am I" & "
what function do I have", in the hope to get some growth from what's happened.
I got several chills and surges running up my back, both during meditation and during my regular days at various moments over some days afterwards. I think it was some kind of adjustment which helped me.
Thanks for your answers.
