The loss of your suggestive triggers thoughts about the observing function. These eventually lead to role function actions. the demonstrative function also comes out if there is a sudden or intense loss of your suggestive.

Eg. without external changes (Ne) SLI will subconsciously think about physical forms (Se), and this leads to planning, waiting, timing things out (Ni role). And if there is a sudden loss of Ne, SLI will instinctively focus their attention (Ti demonstrative) on the cause.
