The actress recently filmed her final scenes as Heather, who exits the soap tonight (March 19) in tragic circumstances.
Fergison last week expressed an interest in appearing on a reality TV show, and today told Loose Women that a programme like Celebrity Big Brother could be the ideal way to show the real her.
Discussing the reality genre, she explained: "Do you know what, I would not say no to any of this kind of thing. I think it's important that people see who you are.
"If people know who you are, it's warts and all, like [my] snoring. Honestly, I had to move a tent in a field once because somebody told me it was that bad. I was camping with a friend, and then three days later they said, 'Could you just move your tent up to the other end of the field?' It was that bad!"
Heather's EastEnders departure storyline sees her killed by Ben Mitchell (Joshua Pascoe) after an argument at her flat spirals out of control.
Fergison commented: "It's a cracker - literally! It's all going to go horribly wrong. It's no secret that I get bumped off tonight, let's put it that way. There'll be no coming back in a taxi.
"Do you know what, it's been brilliant - playing Heather for the last five years has been amazing. I've had a brilliant time at EastEnders - you make some brilliant friends. Steve McFadden, who plays Phil, and Linda Henry, who plays Shirley, are like my brother and sister in real life. So it's fantastic, I've had a great time there."
The 48-year-old also vowed to carry on watching EastEnders as she is a long-term fan.
She said: "Of course I'll carry on watching. Everybody else should carry on watching, because it's a cracking, cracking show. I'm going to miss Hev and I'm going to miss all the people there, but thank you so much for supporting me, I'm really humbled by it."
EastEnders airs Heather's final episode tonight at 8pm on BBC One.
