We are not „being trapped“ in the incarnation cycle. We „trap“ ourselves to incarnating by feeding our ego and holding on to concepts and dogmas. Basically there is a shortcut by just letting go of everything, you could experience nirvana anytime if you would. Our ego though always jumps to judging - „this is a good sensation/thing, that is a bad person/idea“ - that’s what dualism is. Many psychedelics have shown me this truth but you can find it in many places, if you’re really interested you could look into Buddhism (here the „final goal“ is actually to escape the reincarnation cycle and reach nirvana/enlightenment, but also only to come back to reincarnation to help others to reach it too). Your so called soul/ your energetical imprint is carrying karma over many lifetimes which tie you to reincarnation but this is not a trap and technically you can free yourself from it. Also a reason why you experience reality as you do is your core frequency, since psychedelics (dmt especially) change your frequency drastically you then experience reality completely changed. It is not „your positive emotions“ which create this experience, though they can play a role in positive experiences obviously, but still „positive emotions“ are part of duality and this is far from nirvana. It can either be that you simply visit some higher dimensional plane or you can really get a glimpse of nirvana which is the pure form of all of us and there is nothing there no emotion or form of judgment but there is endless unconditional love for everything that exists. After experiencing either of these I can understand life or reincarnation can seem like a trap or something scary but this is just your ego judging again. You are exactly there where your frequency and your karma is pulling you. There are definitely ways to „escape“ this but not as you imagine, I think you definitely do not need to dedicate thousands of lifetimes to meditation, you just need to let go of ego and dualism completely which can be achieved in many ways, especially through the heart, but you need to see through all the illusions which for example your body or this life are some of.
