The Buddha taught that people are born, die, and are born again — this is called "rebirth." But he did not say that "the 'me' I am now turns into a soul that lingers after death and moves on to the next life." A sūtra called the Madhyamāgama preserves an episode about exactly this point.
We think "this is me" as we see with our eyes, hear with our ears, think, and feel. In the sūtras, this activity — of sensing and thinking — is called "consciousness" (viññāṇa).
Long ago, there was a monk named Sāti. Sāti thought: "This very consciousness is the soul that passes unchanged into the next life. Even when it leaves the body, it speaks, feels, and receives the results of its actions." In other words, he believed, "Even after death, the self doesn't disappear." How did the Buddha correct this view? Read the passage that follows.
- Translation
- Consciousness arises through conditions. Where there are conditions, it arises; where there are none, it ceases. Consciousness is named by whatever condition gave rise to it. When consciousness arises dependent on the eye and visible form, it is called eye-consciousness; and so too for ear, nose, tongue, body, and mind-and-phenomena. Just as a fire is named by whatever fuel it burns — a fire that burns wood is called a wood-fire, a fire that burns grass and dung is called a grass-and-dung-fire.

識因緣故起,我說識因緣故起,識有緣則生,無緣則滅,識隨所緣生,即彼緣。說緣眼色生識,生識已說眼識,如是耳、鼻、舌、身、意法生識,生識已說意識。猶若如火,隨所緣生,即彼緣,說緣木生火,說木火也。緣草糞聚火,說草糞聚火。

The Buddha's answer is the opposite of what Sāti thought. Consciousness does not exist on its own, beforehand. It arises when the necessary conditions for consciousness to function — such as the eye and a visible object — come together, and when the conditions change, its functioning changes too. It is just like a fire, which comes to life when fed with wood or grass as fuel, and goes out when the fuel is gone. So the claim that "the consciousness of someone who has died remains in the house as an unchanging spirit, causing accidents and theft" — this claim is nowhere to be found in this sūtra.
Then, if no soul transmigrates, how do the results of our actions continue? Buddhism teaches that it is not a soul that carries the results, but rather that our actions themselves become the conditions that give rise to the next results. Let's confirm this way of thinking in the Saṃyuktāgama.

- If the one who acts and the one who experiences the result are exactly the same, one falls into eternalism. If the one who acts and the one who experiences the result are completely different, one falls into annihilationism. Avoiding these two extremes, the teaching is given from the middle way: When this exists, that exists. When this arises, that arises. With ignorance as condition, formations arise — and thus the whole mass of suffering comes to be. When ignorance ceases, formations cease — and thus the whole mass of suffering ceases.

自作自覺則墮常見,他作他覺則墮斷見。義說、法說,離此二邊,處於中道而說法,所謂此有故彼有,此起故彼起,緣無明行,乃至純大苦聚集,無明滅則行滅,乃至純大苦聚滅。

The Buddha taught that our actions have results. But he did not teach that an unchanging soul carries those results. Read these sūtras, and they do not add up to a claim that "an ancestral spirit remains in the house, causing accidents and theft."
