sentir and sentirse

Question

I get that sentir goes before a noun and sentirse before an adjective. But in a test the question was "Yo siento que voy a explotar, comí demasiado."

How do we know whether to use sentir or sentirse in a sentence like this?

Answer

Hola Peter
In the lesson we also say that sentir can be followed by a subordinate clause using "que" and we give this sentence as an example:
I feel that my husband and I are drifting apart.Siento que mi marido y yo nos alejamos.
This is following the same structure as the test-question:
Siento que voy a explotar, comí demasiado.
If you think about it, this subordinate clause could be replaced by a noun:
Siento algo
Siento una cosa
