Honestly I've never seen, heard or sensed the presence of my guides so I can even say I don't think I have any. But when I started to delve into spiritualism, I read it somewhere that guides can communicate with you in odd ways, especially through syncronicity. When I finally turned my interest to spiritualism and past life research, I got flooded by strange coincidences every day, for weeks. They led me to past life memory scenes, or on other days, the scenes led me to new informations, and in the meantime I got hints in my everyday life. People around me acted like NPCs who just wanted to say a key word or sentence to help me unfold a certain past life. These can look so organized/planned that I don't think it is possible without some "helping hands" from an other plane. Those who believe in god/gods may say that it's God who does all these, but it's not my personal belief.
Before I got the feeling that I want to find out who I was in a previous life, my life went nowhere. I felt I stucked and I didn't get the reason behind my existence. I wasn't constantly depressed, but I wouldn't have minded accidentally being hit by a falling piano on the street.
Many people think that being reborn again and again is a punishment, but I never had this thought in my head, even if it's not guaranteed that I'll have some super fun lives after this one. My completely flat life went through many good changes since I became more spiritual, It's like looking at life events from "above". Now I have the ability to avoid clinging on bad events cluelessly, so I can try to understand their meaning and purpose in my life.
My father whose father died when he was a teen, was unable to overcome the loss in his entire life. In fact, it's getting worse for him, even though his father died in the 1960s. My father is absolutely not spiritual and religious, so he's walking on a slippery ground, not finding an answer to any of his negative life events. It's sad, because I think he's just working with some bad Karma (if Karma exists, if not, then his soul just chose this heavy lifepath to grow). Once I told him that his life wouldn't have turned out to be the same without the losses and bad life events he had. They all shaped him, but he just doesn't get what I try to say.
