Helaena Targaryen's dragon dreams in Season 3 Episode 7 of 'House of the Dragon' do more than warn of the coming civil war. Her latest visions appear to stretch far beyond the Dance of the Dragons, with imagery that many viewers believe points directly to the Long Night and White Walkers seen nearly 170 years later in 'Game of Thrones'.
The haunting sequence has sparked widespread discussion among fans, who see it as one of HBO's clearest attempts yet to link its Targaryen prequel to the events of the original series.
