A recent bailiwick usher that medical students who had negatively charged dream about an exam the dark before did well than those student who did n’t . The effect declare oneself financial support for theThreat Simulation Theory , which suggests we dream as a manner to make for real - living threats .
10 theories that explain why we dream
This is a very bang-up survey with four chief take - aways :
Most aesculapian bookman dream about an exam before the exam — like , upwards of 60 % !
educatee primarily ambition of failure , being belated , and being ineffectual to respond the head
Surprisingly , dreaming of an test predicts gamey performance on the exam
The dramatization of concerns during dreams may train the brain as per Threat Simulation Theory
Thestudy , which now appears in Consciousness and Cognition , was take by Isabelle Arnulf from Paris - Sorbonne University . The abstract furnish a very tidy summary of the effect :
We essay whether dreams can previse a stressful exam and how failure / success in dreaming affect next - day performance . We collected information on students ’ dream during the night preceding the medical schooltime entering examination . Demographic , pedantic , sopor and aspiration feature were compared to the students ’ grades on the examination . Of the 719 answerer to the questionnaire ( of 2324 total scholarly person ) , 60.4 % dreamt of the exam during the night preceding it . problem with the exam appear in 78 % of dreams and primarily tangled being later and forget solution . Reporting a ambition about the exam on the pre - exam night was associated with better performance on the exam ( phosphorus = .01 ) . The frequency of dream worry the examination during the first term forecast proportionally gamey carrying into action on the examination ( R = 0.1 , phosphorus = .01 ) . These results suggest that the negative anticipation of a nerve-wracking event in dreams is uncouth and that this occasional computer simulation provides a cognitive amplification .
There is another theory . Perhaps citizenry who dream about pending exams are more emotionally vested in the result and/or are more serious about study for it . This could very well excuse why they ’re having dreams about it , and why they fare well than those students who do n’t stargaze about it . So the dreams themselves may not be factor in into the result .
