In the 1950’s, dream researchers commonly thought that dreams were predominantly a black-and-white phenomenon, although both earlier and later treatments of dreaming presume or assert that dreams have color. The first half of the twentieth century saw the rise of black-and-white film media, and it is likely that the emergence of the view that dreams are black-and-white was connected with this c...

In the present paper, we present an argument and an initial model connecting research into the functional role of dreams with simulation theories. Traditionally, although theories that describe the refinement of simulations exist, the origin of these simulations is not considered in detail. Similarly, research into the functional role of dreams tends to focus on adults, with less regard to the ...

BACKGROUND Images evoked immediately before the induction of anesthesia with the help of suggestions may influence dreaming during anesthesia.The aim of the study was to assess the incidence of evoked dreams and dream recalls by employing suggestions before induction of anesthesia while administering different general anesthetic combinations. METHODS This is a single center, prospective rando...

Freud’s (1) theory of dream recall explains low dream recall frequency as a consequence of repression. According to his theory, dreams containing unacceptable drives or wishes which were not sufficiently altered by the dream-censor are repressed to prevent conscious knowledge of these contents. If one views repression as an inadequate coping strategy, low dream recall would reflect poor adjustm...

In the past, several studies have been carried out to analyze the effects of various psychoactive drugs on dreaming, e.g., LSD (1), imipramine (antidepressants) (2) or other drugs (3). These studies were almost always investigations on effects of temporary drug administration and on normal volunteers subjects. Effect of psychoactive substances abstinence or cessation, on dream content of chroni...

A variety of empirical studies investigated the dream life of different psychopathologi-cal patient groups in order to shed more light on the inner processes taking place in these pa-tients and possibly find clues as to underlying etiological mechanisms (Overview: 1,2). The basic assumption underlying these studies is the so-called continuity hypothesis which entails that waking life occurrence...

The DreamThrower is a novel technology that explores virtually creating, throwing and catching dreams. It detects users’ dream state by measuring rapid eye movement. Once the dream state is detected, sound and light stimuli is played to alter the dream. Users report on their dream, and they can send the stimuli that they have used to another person via an on-line website. A working prototype ac...

Background: Infatuation and lovesickness are widespread and significant experiences in adolescence. Less is known about the connection between infatuation/lovesickness and sleep. The few studies, examining the link between infatuation and sleep quality show inconsistent results. The link between lovesickness and sleep as well as the link between infatuation/lovesickness and dreams has not been ...

A variety of studies in dream research focused solely on the effect of waking life on dream content (overviews: (1-3)), even though several studies (4-8) indicate that the reverse relationship, i.e., dreams affecting subsequent waking life, can also be encountered frequently. Similar to the findings supporting the continuity hypothesis of dreaming (9) which states that waking life is reflected ...
