I started having past life dreams as a toddler or maybe I carried them over and slowly forgot them as a kid. But, I know they started back up in my 20s after a NDE. I couldnt make sense of them. I basically went through what you are describing...until I decided it wasnt real and I let it go...each one. I had convinced myself it was nonesense and craziness, or an overactive imagination with no facts to back it up. Things kept happening and I kept ignoring them. I started having dreams that were showing me the past life, present life and future life all playing out at the same time. I was stumped...then I started having premonitions...and well there was no ignoring those. It was right in my face, loud and clear.
The lesson was, those feelings or energy in the past life...it doesnt change just because you die or run away from a problem. The only way it changes, is by dealing with it and handling it in a way where either you are being true to yourself and making peace or you were meant to create something more. I saw that feelings can stay the same in this life, as it was left in the past life and will continue to be that way in future lives if nothing is done to change it. It is important to handle situations with care and patience...because often those we hurt, are our soulmates, soul families, and ourselves. Those same lessons just keep coming around until they are resolved in each lifetime...sometimes they get so bad, people that we once loved in another life, are carrying unconscious pain in this life because of the mess we made in another life. The same as we do. Our feelings are very much apart of our energy and soul...all good and bad resides in our energy field/aura. The problem with this, is that you can not rise to the higher levels/consciousness or heaven if you are still being dragged down by the lower levels of other energy...because if something traumatic has happened, there is a certain amount of anxiety/depression that affects all parts of our lives...and it is carried over into each life on some level.
Here is an example...if you get mad at your partner in this life, say for infidelity...and say, you commit suicide (I have seen this scenario many times with people) There is a good chance, because the energy is traumatic and high energized, that the partner will be carrying those feelings over of abandonment, grief and depression into future lives because of the guilt and grief, and you may be carrying unconscious feelings of betrayal, grief and mistrust into your future lives,(this is just one side of it) setting each person up over and over to relive some level of these events because it is still in their energy field. Those feelings have to be resolved and made peace with. We make our experiences here, by the energy behind our thoughts and feelings, so if these events from past lives are still lingering around, they are still there in hindsight waiting to replay out in another scenario or drawing you towards the partner from a past life for better or worse. You know you hear those words, true love never dies? Well, neither does true hatred...its what you do to change the energy, that changes it...and believe it or not...if you are walking around with these bitter feelings and experiences from one life to the next..you are spreading the negativity to others as you form relationships with them.
Understand that one can not die, energy does not die...it changes form and changes vibrational frequencies, but it does not disappear. Let go of attachment and let it be. You are being shown these things through a "gift" or different perception...it doesnt change the outcome, you do...but it is much like giving a half blind child a pair of glasses...or a deaf man, hearing aides. You still have to go through it, you are still not perfect, but now you can see things from the outside instead of being in the middle of the storm if you pay attention.
