Based on prior knowledge, the feature "Oldpeak" represents the ST depression induced by exercise relative to rest measured in depression units. In the context of coronary angiography, a higher value of Oldpeak indicates a higher possibility of heart disease.

To analyze the relationship between the feature "Oldpeak" and the target variable "heart disease" indicated by the coronary angiography, we should consider the typical values of Oldpeak for each target class ('no', 'yes').

Based on this analysis, here is the generated dictionary:

```json
{
	"no": [0.5, 1.0, 1.5, 2.0, 2.5],
	"yes": [3.0, 3.5, 4.0, 4.5, 5.0]
}
```

Above, we have included 5 typical Oldpeak values for each target class. The 'no' class represents patients where coronary angiography does not show heart disease, while the 'yes' class represents patients where coronary angiography does show heart disease.
